Had a neighbor pass away last year, he was 53. He'd smoked pot since he was kid. Typical example of a drug fried brain. Couldn't say a complete sentence without a "duh" and a "uh" in it. He had medical problems and the doctor told him......no drugs or alcohol with your medicine. Didn't listen. Family tells everybody he had a "reaction" to his meds. Yeah, he reacted alright.....by not paying attention to what the doctor told him, and it cost him his life.

That describes a lot of the drug users. Many of them are simply so far out there, that they are either unable, or unwilling, to comprehend that what they are doing is dangerous to themselves, not to mention others.
