I’m 52 years old and have been using cannabis on and off since aged 14. I earned four university degrees including a law degree from a T-15 school, which I chose over a number of T-10 schools that accepted me because I wanted to be in DC. My life has been generally successful although I have struggled with PTSD from childhood with abusive alcoholic father and enabling abusive mother. Cannabis has never caused me any significant issues, including the super good stuff I can get at the dispensary down the street these last few years since we legalized.
I was a prosecutor and defense attorney for years and I can count on one hand the number of cases I had involving cannabis and violence - and those involved a mixed intoxication of alcohol, not just cannabis. From my own life and professional experiences and years of reading the research, I know without doubt that the truly great evil in our society is ALCOHOL, period.
Anyway, there ARE laws regulating cannabis use in DC, so the OP and others here are engaging in disinformation.
