I think it's a bit of both. I was a chronic user when i was in my twenties, accompanied with pills, DF'S, Vallies, Morphine or E and beers or vodka. But when I hit 30's I ditched all the pills and had a hard look at life, I was going through women, promising them and myself she is the one, she never was. Come the 40's I did find my woman stopped the weed, just because we have moved to a safe part of the country, but still popping pills when I get from doc.
Why am I telling you my life, I don't know, I know I don't cough in the mornings like I used to so that's a plus
