so i got caught....

you're 20 years old, man up. the other day i was burnin a j and my mom was in the kitchen. i did this a few times and i havent a clue had she never known i was smokin right in the next room, the living room. maybe cuz my brothers smoke cigs all the time. she comes in the room and says whats burning. i show her the spliff. its funny cuz she acted all surprised. she knows im growin a plizant, i leave weed bags, weed and my ez wides lyin around all the time, i got high times sittin on my lil table. she shoulda known what i was doing. on top of that she knew i smoked. it did feel weird smokin in front of her though. i felt umcomfortable.

Well it could be a good argument to mention that it's okay with him to drink alcohol..which is a nerve destroying poison that causes many thousands of deaths a year..yet he doesnt consider it a drug, and that cannabis actually protects the brain (it doesnt kill it like alcohol) and improves health. For more click "marijuana" in the link in my sig

Its true what Euphoric said. There have also been recent tests on rats (I know, theyre brains arent exactly the same as ours, but this is still a HUGE discovery) with cannabis. They found that cannabis/THC in rats acted on their brain - but in a good way. A VERY good way. It actually 'rebuilt' cells in the part of the brain that deals with emotions.

You can tell him Euphoric's signature:::
WAR ON DRUGS : $500 billion
Citizens arrested: Millions
$ that could be saved in a year if we legalize drugs: $37 Billion
Getting high every day despite it all: Priceless

Hahaha!

But, if it where me in that situation?

DUDE! He's trying to convince YOU... why should you lay everything out for him???

Tell your uncle to go to his computer during the week, do some research... read a lot of stuff, and come back to you the next weekend with the information... that way, you can both discuss what he has found.
Why the fuck should YOU make all the effort? If you're just bound to get shot down...
