Just a short, opinion-based question.
Assuming you have pure cocaine HCL (IN), and MDMA HCL (oral)
What do you think causes a stronger crash, and even though dosage is a big factor, lets say its a "sweetspot" MDMA dose somewhere around 150mg, which would last 4-6 hours... so however many MDXX High pills it would take to take you to your personal sweetspot, and however much coke you need to keep a moderate buzz going for also 4-6 hours.
The reason i dont specify doses is because with MDMA, i can be good with 1-2 good rolls (i never need more than 2, and 1 always does the trick, the second is usually used to boost), so for me im comparing about 120-150mg of MDMA to about a gram of decent potency NYC coke. However, some people i know drop 5-12 rolls in one night, and are ready for a second go the next day (only to be disappointed, of course), and while 2 "okay" lines is enough for me to start a coke buzz, i know someone who needs at least a gram or 2 to get to the same place.
PS: Funny story, a friend once was trying to be classy, railing upper east side blow with a hundred dollar bill, and he was doing line after line until he started to bleed from the nose, which he didnt notice at first. The result was a hundo dripping with blood, and it aint easy to break a hundred dollar bill at the closest deli when its covered in blood (but he got it done, lol, the # was still undamaged and by law it is still acceptable, it wasnt torn or anything)
Also, after thinking about whether this should go into ED or OD, i decided OD is probably better for this thread, as coke is covered here, and only MDXX is usually covered in ED.
