In my life I have mostly used marijuana with some alcohol and pharms, (xanax ativan vicodin etc) I have also done acid twice, and shrooms once. all times were phenomenal experiences, as far as the actual high. In fact I always suspected I have an especially high tolerance for drugs. On the other hand Ive done five adderall pills, with no results but staying up all night. Ive taken ecstasy four times, only feeling it once, when I took two pills, and all I felt was a four hour head rush and rapid speech. no euphoria. caffeine does nothing to me. Cocaine might do something, I did it five times, but felt it once, although this may have been due too a dosage issue, not a natural tolerance (Im fairly large). I recently tried eating a significant amount of mescaline cactus to no avail. Is it possible I have a natural tolerance to phenethylamines? or is it all stimulants perhaps? If there is recorded evidence of this happening?
i seem to be the exact way... ex, shrooms and weed are the all around best hight for me, when it comes to coke or caffine i get no results.
Stick with what works. Benzos take a while to get out of the system and will lessen stimulant effects somewhat. SSRIs will weaken the effects of some phenylethylamines, especially MDMA. You may also not be producing much dopamine, or serotonin, in which case those drugs will have lower effect. You could try supplementing with l-tyrosine, 5HTP, or (carefully) a natural source of L-dopa. It might be that stims just aren't for you.

Benzos may be the problem. Wrong cactus? Maybe. If it's real and nothing iterferes, the trip should be incredible.
I would go with a natural tolerance. Tolerances are very different for all kinds of people. I can take 1 vivarin (200 mgs caffiene) and be buzzing hard for 3 hours, while my friend can snort 300 and go to bed within five minutes. Stick to what works to avoid wasting money on drugs that barely affect you. Have fun and be safe! The Mushroom Man
