lol. i remember back in 1971 we got some extra good mex, man i just smoked a little bowl out of a deer horn pipe and i was trippin for hours, ( the sex was outstanding )Mexican bagseed I grew out myself that was obviously a pure sativa and had me tripping balls nearly out of body experience type buzz and not like any of the modern strains it's a whole different kind of high almost like a different drug. Find some good old school mexican herb and grow them outdoors under the sunlight so they develop ample THC-V and you will get right where you want to be at brother. That is where the trippy component comes from in some strains from the research I have done, you want strains rich in THC-V
Malawi Gold is a great place to look as many African strains are very trippy. Nigerian, Durban, African Sativa's ect.
Cindy 99 can also be very trippy when harvested with clear trichs but with that comes some racy paranoia & that typical rushing anxiety that some people can't manage well. I don't like it myself and if I smoke cindy it's always fully done and amber fully cured which mellows it out alot.
Freshly dried buds with all clear trichs is where the highest levels of THC & mind bending potency are to be found, once plants start going amber the THC levels are decreasing. Once buds are properly cured out the buzz normally mellows out as well and is less intense in my experience.
So Sweet Tooth definitely does not fit this bill though sorry guys I can't recommend it for being trippy but I will look for other threads though so don't worry!
