The Dirty Dozen #3: High-Potency Marijuana and the Risk of Addiction
By Laura Stack
When 10-30%+ of all frequent marijuana users depend on it to get through the day, you have prima facie evidence that a substance is addictive.

Yet another similar story. Our son (20 as well) became psychotic after ingesting a 50 mg edible on his birthday (6/10) while he was also going through a dab cartridge every few days. He became increasingly paranoid and angry (180 degree turn from his usual gentle nature) to the point where he was so aggressive I had to leave my own house. … Read the rest
