The most common behavioral effect is a decrease in psychomotor activity. This effect is determined by the size of the dose: the larger it is, the more noticeable this effect. A general disturbance of motor activity is pervasive and is characterized as a state of relaxation and calm. The only exception to this rule is speech, since Smoking marijuana gives rise to quick speech, detailed talk and talkativeness. These effects are more often observed in the initial phase of smoking, followed by more traditional relaxation.
Although feelings of relaxation and well being are common when cannabis is used, some people who use it first feel agitated. However, soon smokers are always experiencing a transition to the stage of relaxation. Moreover, besides the feelings of relaxation, those who use testify to an increase in sensations. Many smokers, for example, describe an increased sensitivity to touch, sight (especially color perception), hearing, and smell. Finally, other studies show a decrease in pain sensitivity after smoking marijuana.
Accompanying sensations of relaxation and deterioration of motor activity is a sharp deterioration in some areas of psychomotor perception. Dysfunction of motor coordination, perception of external impulses and the ability to observe an external object depends on the size of the dose. If such factors are taken into account in aggregate, then they will undoubtedly affect, for example, driving a vehicle after cannabis use. Laboratory experiments that included an experiment with a driving simulator showed the devastating effects of cannabis on driver abilities and skills. Some of these impairments in driving skills can be identified. It turned out that the driver, who is under the influence of marijuana, shows impaired concentration and distance determination, along with the deterioration of all other driving skills. It is possible that some deterioration in driving skills may be due to an increase in sleepiness, as a result of which there is a deterioration in the perception of peripheral signals. Psychomotor disorders can be caused by cannabis, and these disorders become more apparent when solving problems that require thinking and concentration.
The impact of marijuana on sexual behavior and functioning is not fully understood, but it turns out that the effects on this area of human activity vary greatly depending on the characteristics of the user. Some report that sexual pleasure after smoking marijuana becomes more intense, intense, while others, on the contrary, speak of a loss of interest in sex. Those who testify to the increase in sexual pleasures in the use of marijuana, probably based on the effect of increasing the sensitivity of sensors, which often accompanies the use of marijuana. The drug itself leads to unknown physiological effects that stimulate sexual impulse or perception. However, prolonged or intense use of marijuana is associated with temporary impotence in men and temporary disorders in the sexual life of women.
