delivered the opinion of the Court.
Defendants, all of whom had previous felony convictions, were each charged in the district court in a separate information with possession of guns in violation of 1971 Perm. Supp., C.R.S. 1963, 40-12-108. 1 In each case, prior to trial, a motion to dismiss was filed, alleging that the statute was unconstitutional. It was contended that this statute was unconstitutionally vague, overbroad, and that it violated Article II, Section 13, of the Colorado Constitution.
The motions were consolidated for hearing and the trial court concluded that the statute, though not constitutionally vague, was overbroad and did violate Article II, Section 13, of the Colorado Constitution, which guarantees the right to bear arms. The district attorney has appealed the ruling and the three cases are consolidated here for review.
1971 Perm. Supp., C.R.S. 1963, 40-12-108 provides:
“Possession of weapons by previous offenders. Any person previously convicted of burglary, arson, or a felony involving the use of force or violence or the use of a deadly weapon, or attempt or conspiracy to commit such' offenses, under the laws of the United States of America, the state of Colorado, or another state, within the ten years next preceding or within ten years of his release from incarceration, whichever is greater, who shall possess, use, or carry upon his person a firearm or other weapon mentioned in sections 18-1 -901 (3)(h) or sections 18-12-101 to 18-12-106, commits a class 5 felony. A second or subsequent offense under this section is a class 4 felony.” 2
We affirm the ruling of the district court that the statute is not unconstitutionally vague, and reverse the ruling that the statute is over-broad and violates Article II, Section 13, of the Colorado Constitution. In

our view, defendants have failed to show beyond a reasonable doubt that this statute, which is designed to protect the public health and safety, is unconstitutional.
People
v.
Summit,
I.
Defendants here contend that the trial court erred in ruling that the statue was not unconstitutionally vague. We find no error in that determination.
Defendants argue that the statute must fall because many of its crucial terms are so vague that a person of ordinary intelligence would of necessity have to guess or speculate as to their meaning. Cited as unduly vague are the words “involving” and “use of force or violence,” and also the time computation section of the statute, reading in part “ * * * within the ten years next preceding or within ten years of his release from incarceration, whichever is greater * * *.”
We have long held that perhaps the first essential of due process is that a statute state its mandate with reasonable clarity. As we said in
People
v. Cardwell,
“That the terms of a penal statute creating a new offense must be sufficiently explicit to inform those who are subject to it what conduct on their part will render them liable to its penalties is a well-recognized requirement, consonant alike with ordinary notions of fair play and the settled rules of law * * *.”
See also People v. Heckard,
“ * * * [F]ew words possess the precision of mathematical symbols, most statutes must deal with untold and unforeseen variations in factual situations, and the practical necessities of government inevitably limit the specificity with which legislators can spell out prohibitions. Consequently, no more than a reasonable degree of certainty can be demanded. Nor is it unfair to require that one who deliberately goes perilously close to an area of proscribed conduct shall take the risk that he may cross the line.” Boyce Motor Lines v. United States,342 U.S. 337 ,72 S.Ct. 329 ,96 L.Ed. 367 . See Cardwell, Supra.
Bearing these basic principles in mind, and also the proposition that any statute alleged to be vague must be closely scrutinized,
People
v.
District Court,
*100
Defendants assert that “involving,” a term not defined in the Colorado Criminal Code, is objectionable. This court, however, has never required that every statutory word or phrase be specifically defined. We have often made reference to standard dictionaries and to the case law to determine the probable legislative intent in using a particular word. “Involve” has been defined as “to have within or as part of itself: contain, include”; “to require as a necessary accompaniment.”
Merriam-Webster New International Dictionary
(Third Edition), p. 1191. In
People
v.
Sell,
Additional citation of authority is not required. “Involving” is a common, readily understood word, and whatever imprecision its use may entail does not rise to the level of constitutional infirmity.
Defendants also contend that “use of force or violence” is extremely vague, citing as support for this proposition
Markham
v.
Brainard,
Defendants finally contend that the time computation provision of the statute is too vague. And again we disagree. Speaking to the “void for vagueness” doctrine, the United States Supreme Court in
United States v. Powell,
“* * * the fact that Congress might, without difficulty, have chosen ‘clearer and more precise language’ equally capable of achieving the end which it sought does not mean that the statute which it in fact drafted is unconstitutionally vague. United States v. Petrillo,332 U.S. 1 ,7 (1947).”
Thus, a statute need not be drafted with the greatest possible facility or lucidity of expression if it meets the minimal requirements of due process. *101 Notwithstanding the fact that the wording of this provision might require more than a quick glance for full comprehension, we find its meaning plain.
We therefore reject defendants’ contentions as to the asserted vagueness of the statute. We reemphasize that the legislature is not constitutionally required to specifically define the readily comprehensible and every-day terms it uses in statutes.
See Broadrick
v. Oklahoma,
II.
The trial court ruled that the statute is unconstitutioanlly overbroad and hence void as a whole, in that it inhibits persons with previous felony convictions from participating in lawful business endeavors and private activities. We disagree.
The statute incorporates by reference and thus forbids the possession, use, or carrying of the weapons listed in sections 18-1-901 (3)(h) and 18-12-101 to 18-12-106, C.R.S. 1973. Defendants cite particularly section 18-12-101(f), which reads:
“ ‘Knife’ means any dagger, dirk, knife, or stiletto with a blade over three and one-half inches in length, or any other dangerous instrument capable of inflicting cutting, stabbing, or tearing wounds * * *.”
It is argued that this section, when incorporated into the “felon with a gun statute,” has the effect of making it criminal for an ex-felon to cut meat with a table knife, repair his car with a screwdriver, or do any mechanical work involving tools capable of tearing, cutting, or stabbing.
The usual rules of standing as developed in Colorado would preclude our finding this statute void as a whole. As a general proposition, no one is entitled to assail the constitutionality of a statute except as he himself is adversely affected.
People v. Stark and
Peabody,
“* * * It is manifest that this Court does not overturn statutes presumptively valid on the strength of the speculations and conjectures of counsel as to what might happen under them.* * *”
Thus, under the usual rule, defendants charged with possession of guns have no standing to attack this statute on the ground that it improperly incorporates an all-encompassing definition of “knife.” We do not examine the outer bounds of statutes where the alleged conduct falls clearly within the statutes’ prohibition. While, as suggested by the defendants, doubts as to the applicability of the statutory language in marginal fact situations may be conceived, we think the statute gives defendants adequate warning that their possession of a gun was a criminal offense. United States v. Powell, supra.
*102
To avoid the standing limitation of the usual rule, defendants attempt to apply the “overbreadth” doctrine. This doctrine, however, has been cautiously applied only in certain limited cases where “weighty countervailing policies” counteract the usual standing requirements,' where important rights would otherwise be threatened. Thus, in the area of First Amendment freedoms, courts have sanctioned “attacks on overly broad statutes with no requirement that the person making the attack demonstrate that his own conduct could not be regulated by a statute drawn with the requisite narrow specificity.”
Dombrowski
v.
Pfister,
We have also held a municipal ordinance to be unconstitutionally overbroad in
Lakewood
v.
Pillow,
These defendants, however, cannot invoke the same constitutionally protected right to bear arms as could the defendant in Lakewood, supra, for, as we make clear below, the right of a convicted felon to bear arms is subject to reasonable legislative regulation and limitation. The overbreadth doctrine, intended as it is to protect weighty constitutional interests, cannot be extended to the circumstances of the present controversy.
III.
We do not agree that the statute violates the provisions of Article II, Section 13, of the Colorado Constitution.
Article II, Section 13, of the Colorado Constitution reads as follows:
“Right to bear arms. The right of no person to keep and bear arms in defense of his home, person and property, or in aid of the civil power when thereto legally summoned, shall be called in question; but nothing herein contained shall be construed to justify the practice of carrying concealed weapons.”
It is argued that the statute, which prohibits possession, use, and carrying of a weapon, is a blanket proscription that cannot be reconciled with the literal constitutional language. A felon is a “person” within the meaning of Article II, Section 13, the argument runs, and once he has served his term he is reinstated to the full rights of citizenship, Colo. Const. Art. VII, Sec. 10, including the absolute right to bear arms.
However, not all constitutional rights are absolute.
Mosgrove
v.
Town of Federal Heights,
We do not read the Colorado Constitution as granting an absolute right to bear arms under all situations. It has limiting language dealing with defense of home, person, and property. These limitations have been recognized by the General Assembly in the enactment of section 18-12-105, C.R.S. 1973, which restricts the right to bear arms in certain circumstances, while permitting in other circumstances the carrying of a concealed weapon in defense of home, person, and property, and also when specifically authorized by written permit.
In our view, the statute here is a legitimate exercise of the police power.
“* * * To limit the possession of firearms by those who, by their past conduct, have demonstrated an unfitness to be entrusted with such dangerous instrumentalities, is clearly in the interest of the public health, safety, and welfare and within the scope of the Legislature’s police power.” People v. Trujillo,178 Colo. 147 ,497 P.2d 1 .
See also People
v.
Trujillo,
Moreover, our view does not abrogate an ex-felon’s right to legitimately use self-defense. The felon with a gun statute must be read in pari materia with section 18-1-702, C.R.S. 1973, which provides in pertinent part:
“* * * [C]onduct which would otherwise constitute an offense is justifiable and not criminal when it is necessary as an emergency measure to avoid an imminent public, or private injury * *
Defendants have not contended that they were armed because of any threat to their lives or in order to defend their homes or property. *104 This could be a defense against unreasonable application of the statute, but is not involved in this case.
Defendants direct our attention to
People v. Nakamura,
In sum, we hold that section 18-12-108, C.R.S. 1973, the felon with a gun statute, is a legitimate exercise of the state’s police power.
The judgment of the district court is affirmed in part and reversed in part, and the cases remanded with directions to reinstate the informations, and for further proceedings consonant with the views expressed herein.
Notes
Now section 18-12-108, C.R.S. 1973. Blue had been convicted of robbery in 1969, and Brown of conspiracy to commit robbery, also in 1969. Ulibarri was convicted of conspiracy to commit burglary in 1971.
