Parents all did it in the 60's & 70's I've recently gotten them and their friends back into it.

If you ever get a chance burn down with some old/x-hippies, great stories (really wish I could find some methaqualone lol, sounds fantastic).
mom-will do it occasionally
step-dad-loves to burn, he's a trip dude is hilarious when he burns he gets on laughing trips and can't breath it's awesome. Agreed Tyler, our relationship is 10x better since we started smoking together.
dad-stays high lol. cool story though 6-7 years ago, don't think he'd smoked for 20 years or so, I had stopped for a year for a job initially, then a gf. anyway, he was going through chemo and just couldn't get any meds to work for pain/nausea/appetite, and he was giving up ya know, not eating... he was just sitting there dying, he was miserable. so I decided to find some nugs, copped a q of some killer dank and took it over w/a bong one night & talked him into it... we ended up smoking all fucking night long lol, I cooked up a huge dinner and he ate his ass off for this first time in months and we chilled/talked/watched mystery science theatre 3000 and he laughed and was happy, just a complete 180 it was beautiful. it helped get him through the rest of his chemo and he's still burning today. %)
