eating the shit works the best for me, you know if its like a quarter or something. as for something like a bowl im going to have to go with the bong, water bong or gravity, they both work well.
im surprised someone hasnt mentioned this. What gets me the highst is switching between pieces every now and then. Ill go through a weekend of smoking just spliffs, then wen the weeks rolls around, pull out my bong and get noticeably higher. after a couple of days i will start to use my vape, then ill just be destoryed. But back to spliffs after that, and the cycle continues. I think you build somewhat of a tolerance to each type of way you use weed, so switchng your piece often gets you the highest.
smoking a lung gets me really fucked up but i perfer a bong or bucket, but nothings better than smoking a j with your best friends
