The pot smoking is because your background anxiety levels are off the charts now that your body is aware of the abuse and violation, it is in hyper-alert mode. If a normal person's anxiety level is a zero or 1, a CSA survivor's could be a 4 or 5, and then spiking from there as he encounters stress.

The pot smoking helps to dial back the anxiety level; this is my daily life.

Recovery is possible. Hang in there, brothers.
