The question of the negative effect of passive smoking is already being discussed not only in terms of tobacco products but also in terms of marijuana . The issue is becoming more important in terms of legalizing marijuana for medical needs in more countries around the world.
Passive smoking has been shown to provoke specific problems with blood vessels . Laboratory tests show that inhaling cigarette smoke and saturating the blood with it reduces the ability of the vascular walls to relax and maintain normal blood circulation. This effect lasts about 30 minutes , after which the smooth muscle in the vascular walls restores its normal tone .
In passionate smokers who smoke an average of 1 to 2 cigarettes per hour, the normal function of the vascular walls can be seriously disturbed, and they will never be able to recover it. This leads to one of the most serious risk factors for active and passive smokers – the risk of thrombosis , heart attack and stroke. Data on this risk for passive marijuana smokers is even more frightening.
A laboratory study conducted in the United States found that passive smoking of marijuana has a far longer negative effect on blood vessels than cigarette smoke. The deterioration of blood vessels in passive smoking of marijuana can last up to 90 minutes or more . Damage to the vascular walls may be even more lasting and may become irreparable when exposed to passive smoking.
The effect of passive smoking of marijuana on the risk of cancer and other serious lung diseases is also being monitored . Scientists believe that this risk is equally high for both types of passive smoking – tobacco and marijuana.
Although it has a different chemical composition than tobacco, marijuana leads to the same, and in some cases even more serious, effects when its smoke is inhaled passively. This necessitates the introduction of serious restrictions on its use in public places even in countries where it is fully legalized for medical needs.
