all this talk of tolerance,
I used several noids for the last 5 years, generally the same one for a year and then move on never really experienced any tolerance issues on basic trials, (JWH-018, JWH-250, AM1220, 5f-AKB48, AF-PB22), but then again I use CBD exclusively and low doses to make sure receptors are not peaked, takes half of a year sometimes 3/4 to build up any type of higher does needed....and some of that is just because of trying to push it to get longer effects than the lower dose provides....
I can stay at 2-3mg for at least 4-5months with these aforementioned noids, hit it and quit it.
are you guys vaping or something? what are your dosages per hit?
I don't think it is fair to asses one cannabinoid when other cannabinoids are also being used, the ones you might favor could be the ones peaking your receptors, thus causing the other ones to have less effect.
A fair trial to me would be take a month off of my normal mainstay, then begin critiquing a new one starting a really low doses with a clean slate and receptors reset to baseline.
