Some Facts You Just Can’t Argue With:
- Smoking marijuana leads to some changes in the brain similar to those caused by cocaine, heroin and alcohol.
- There is 50-70% more cancer causing material in marijuana smoke than in cigarette smoke. Although it’s constantly promoted as “all natural,” marijuana smoke contains more than 400 chemicals.
- THC (or tetrahydrocannabinol), the primary intoxicant in marijuana and hashish, is rapidly absorbed by fatty tissues in various organs. Generally, traces (metabolites) of THC can be detected by standard urine testing methods several days after a smoking session. However, in chronic heavy users, traces can sometimes be detected for weeks after they have stopped using marijuana.
- Long-term marijuana use can lead to addiction.
