Alcohol and Drug Abuse

  • Effects of Smoking Marijuana

    In our experience, the effects of smoking marijuana use typically cause decreased activity in the posterior temporal lobes bilaterally.

    The damage can be mild or severe, depending on how long a person used, how much use occurred, what other substances were used (nicotine is a powerful vasoconstrictor) and how vulnerable a particular brain is.

Anxiety

  • Increased basal ganglia activity

    social withdrawal and conflict avoidance. Increased activity in the temporal lobes has also been associated with anxiety.
