Long Term effects of Marijuana

• Addiction to Marijuana.
• Short and long term memory loss.
• Rewiring of nerve cells containing dopamine.
• Mild increase in addiction vulnerability.
• Decreased ability to deal with stress.

These symptoms occur in fewer individuals:

• Depending on the method of intake, smoke from the marijuana can cause lung problems including coughs and colds, emphysema, cancer.
• Higher incidence of schizophrenia. It is currently unknown whether Marijuana may simply be a trigger for those already vulnerable to the disease, or a cause.
• Psychosis.
• Permanent impaired coordination.

It depends on the person, I have some friends from college who are heavy marijuana users and has definitely made them"slower" - At the same time, I graduated pre-med with a heavy user who is as sharp as a tack- It enhances your personal characteristics- he's now a well known doctor, if you are a stupid lazy bum you will be a stupider lazier bum over time- if you are intelligent and use it to relax and accommodate your needs you should be doing great!
