2c-x's prdouce a fair amount of tolerance with day-to-day use. In my personal experience dosing 20mg one day would be equivalent to 35mg the next day with 2c-e both administered orally. JWH's have similar tolerance, I'd have to vape at least 3x the dosage of the previous day to receive the same effect. I also have a fairly high thc tolerance and there is some cross-tolerance between the chemicals.
i probably agree with this. i took 16 mg 2ce once, and 17 mg the next day - with not as strong of a trip though. maybe about 3/4s as strong. i recall with acid i once took one hit, then another the next day, maybe two i'm not sure...and NOTHING happened.
jwh 018 tolerance is different than psychedelic tolerance - let me explain. say if you take alotta acid in one day, and then the next day you take the same dose you'd obviously NOT trip as hard - but JWH 018 gives more of a long term tolerance, but not a short term tolerance; meaning that you could get extremely baked on JWH 3 times in a day but you could really only have 'one' trip in a day. i got to a point where I was smoking jwh 018 3-4 times a day, and with a bit of a tolernace its actually nice cause you don't get as BAKED as you do your first times smoking it, but after a week or two of smoking 3-4 times a day you need like 15-20 mg bowls to get you ripped, compared to 2-3 mg initially which would you get you baked. when you get to the point mentioned above, just take a week tolerance break and you should almost be back to base tolerance levels... it's just so hard to take a tolerance break on JWH 018 when you have a gram baggie staring you straight in the face and you think "ahhh just this time, I'll take a tolerance break after this" - until you've smoked that whole gram of it within a few days (no joke I've done that)/
