DON'T TRIP ON DXM BY USING CORICIDIN COUGH AND COLD! C.C.C. has an extra active ingrediant which can kill you. Use Robitussin products or if you are in Canada get Contac CoughCaps because they contain nothing but 30mg of DXM.
good effects (what people take it for):
-altered time perception
-"cartoonish" tint to vision
-static-like tint to vision
-visual and auditory hallucinations at high doses
-delirium (thinking that a tree is talking to you, etc.)
-intense euphoria (happiness)
-strong feeling of connection with others (compared to the effects of ecstasy)
bad effects (what people hate about taking it):
-possible nausea and vomiting (depends on if you have a weak stomach or if you are nervous)
-possible paranoia (depends on mood and surroundings)
-decreased sex drive (not only does the thought of sex never cross your mind, but even if it does you'll find it extremely hard gettin a boner or gettin in the mood)
-pupil dilation (dead giveaway if you're on it, i reccomend staying away from parents or other people who can't know that you're tripping, or at least never looking them in the eyes)
-"bug eyes" (makes it look like you're scared or surprised all the time, which can also be a giveaway that you're on something)
-increased heart rate (dangerous if you have heart or blood pressure problems)
-zombie-like walking (makes it look like you're hypnotized, which can also give away that you're on something)
overall a great drug to take for a legal high, can be found in medicines such as coricidin cough and cold, robitussin cough syrup,...
(dextromethorphan was mis-spelled in the first definition)
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.
