i never really have noticed any distinguishable "plateaus" on dxm...for me i have the same effects no matter how much i take...just weaker or stronger depending on the amount.
my first time i got to the third and beginning of the fourth plateau.. it was the best thing that ever happened to me. i experienced ego death and i didnt care literally about anything. one crazy ass drug
Some nut should go to the drug store and set the fucking DXM shelve on fire in the name of Legal Cannabis.. FUCK OFF AMERICA!!!
