In psychological theory, the positive aspects of smoking can reduce the mental stress of patients and normal people (because smoke contains chemical components that anesthetize the spirit);

But it is more negative:

1:. Very harmful to the body (easy to cause constipation, acne, large pores, blackheads, etc. Severe cases can lead to lung cancer. Gastric cancer, sinusitis and other diseases) 2. Psychological harm can not be ignored, which is easy to cause mental dependence (that is, psychological mental dependence) and will never lead to smoking addiction. 3. It is easy to cause cerebral nerve paralysis for a long time, and there will never be a situation of mental trance and inattention.

I hope I can help you.
