Although cannabis can cause certain physiological effects, most of them differ from one user to another, and not only their strength and intensity, but also their duration. Basically, the strong physiological effects of marijuana are not dangerous for a healthy body. Indeed, the Ledine Commission (1972) reported that “the short-term physiological effects of a standard dose of cannabis for normal people are mild and do not have much clinical significance.”
The most typical effects are those of the cardiovascular system. Predominant among them is swelling of the mucous membrane of the eye or inflamed eyes. This effect, which occurs as a result of dilation of blood vessels, most often occurs within an hour after smoking and is largely determined by the dose. Although some also noted that pupils are also dilated after smoking, studies have not supported such statements. This is probably most often caused by the fact that marijuana is smoked in a dark room. However, cannabis can somewhat slow down the response to light.
The second most common effect of the cardiovascular system is an increase in heart rate and an increase in heart rate. Both of these effects appear within an hour and both are determined by the dose volume. Maximum heartbeat occurs 20 minutes after smoking. In addition to these effects, blood pressure may increase slightly. There is no evidence that these effects cause irreversible damage to the normal cardiovascular system.
Another common effect of cannabis use is impaired motor function. The only exception to this can be considered a talkative mood. Some smokers show a feeling of relaxation. Cannabis can also affect various stages of sleep, partially affecting the function of PEM. However, this happens mainly with large doses of cannabis.
Other effects, which are evidenced by the patients, may be insignificant or just rare, and, more often, they are different in different people. These effects include (but not limited to) the following: dry mouth, the appearance of thirst, fluctuations in breathing and body temperature, feeling hungry or swallowing saliva (especially strong within three to four hours after smoking), nausea, headache and / or dizziness .
