I'm over 40 and smoke occasionally (perhaps 2-3 times a year) Marijuana is not addictive, not for me anyways and I've never had any bad trips (I grown my own and do not buy from black market sources)

I am a creative person and I find that a J allows me to gather my thoughts in ways that i could not have perceived before. I also become more in tune with my emotions and the emotions of people around me... The whole experience stays with me as I learn from it.
