First, the harm of marijuana
1, psychological dependence
Marijuana dependence is mainly psychological dependence, physical dependence is light, and it is not easy to produce tolerance. Usually a small amount of inhalation or intermittent use of large doses will not produce withdrawal symptoms, and withdrawal reactions are more common in people who use large doses in widely endemic areas. Sudden withdrawal can lead to excitement, anxiety, loss of appetite, insomnia, hypothermia, and even chills, fever and trembling. It usually lasts for 4 ~ 5 days and gradually disappears.
Changes of mood and mental state: within 1 ~ 2 minutes after smoking marijuana, there may be short-term anxiety, inexplicable vague anxiety and irritability. After a few minutes, I will enter a bright and cheerful period, feeling particularly stable, comfortable, relaxed and happy, feeling that everything is beautiful, full of happiness, and hearty and enthusiastic to others. Kan Kan is very talkative, and he really wants to find someone to say a few thoughtful words to share his happiness. After that, I slowly turned to the intoxicated period, quiet and complacent, no longer wanted to talk to people, and wanted to be immersed in ecstasy alone.
Perception: Dependents generally feel vivid, rich and profound about colors in a quiet mood, and feel that things around them are colorful. The ability to appreciate music is enhanced, and it is more sensitive to other sounds. Touch, taste and smell can all be enhanced.
Thinking and association: I feel that my brain is better and my work is more competent while my perception is changing.
