Hi excuse me for my random English I’m French and tired, I hope it’s still comprehensive ☹️

I have a problem with my speed it stopped working on me after my second session, yesterday I took 25 line of 20mg - 40mg every 1hours and it worked well but the next day I tried 50mg orally and after 2 hours i just felt a bit euphoric nothing more so I snorted like 5 more lines still no effects.

I am pretty sure it’s not due to my tolerance or my life style, I eat well sleep well drinks a lot, but maybe it has something to do with my ADHD ?

I can add more precision if it can help :

I’m ADHD but I never taken any medication or stims since my 19’, recently I tried NEP, 2,3MMC, 4f-methylphenidate and cocaine (it doesn’t make any effects to me) and I experimented the same wired thing that with speed after the second or third day it stop working.

ANYWAY PLEASE HELP ME OR EXPLAIN ME WHAT IS HAPPENING !!

*Also I bought my speed from the DW to a reputed vendor, i dried until its looks like white flour.
