DXM
A powerful disassociate psychogenic, usually gathered from cough syrup. It is a synthetic opiate replacing heroin and opium in old-time syrups. At a low dosage (30-60mg), it suppresses the cough center of your brain.

At higher dosages (500mg-2000mg, depending on weight), it is a powerful full-blown psychogenic that can cause major OBE, time distortions, hallucinations, and a general disassociation from reality (hence it's a disassociate).

People who don't like it usually a) can't handle the intense experience or b) tried drinking cough syrup too much. It can be legally ordered as a pure powder from many net sources, and rather cheaply (cheaper than syrup).

It's usually measured in "plateaus", with one being the lowest (500 or so mg) and four being the highest (1.5G+), with each stage getting closer to full-blown hallucinogenic disassociation.

If you haven't done at least 500mg (around 1 1/2 of Robo MS), then you really haven't tried it.
I dexxed heavy last night and had a Philip K Dick experience out on the front porch...but it wasn't the same front porch as ours. It was...somewhere else.

DXM
The drug dextromorphan hydrobromide, found in cough medicine. Many cold medicines have acetaminophen, which will kill you if you overdose. So be careful.
This cough syrup has a lot of DXM, but the psuedoephedrine, chlorphineramine maleate, acetaminophen, and guaifenisen will kill you if you try to trip on it.

DXM is a dissociative hallunicogenic drug found in most cough syrups. It's recreational dose ranges from 100-2,000 mg. Most reccommend that you NEVER take more then 20mg/kg (1 kg=2.2 pounds) or take anything that has ative ingredients other then Dextromethorphan (which DXM is short for) as you can overdose. Effects can be felt with around 2mg/kg on a half full stomach with most taking 3-10mg/kg. When you go above 8 it becomes less euphoric (aka fun) and more hallucinogenic (weird).
The plateaus are:
1.5-3mg/kg= 1st
3-8mg/kg=2nd
8-15mg/kg= 3rd
over 15mg/kg= 4th

Be aware your pupils will become dililated badly and will stay dililated for a while even after the effects wear off and its easy to tell when someone's on it (almost as easy as alcohol) and you might puke.
I took 43 coughgels of DXM and she took 17, but she's more fucked up then me!
