The topic is legal and herbal highs has been causing a stir in America recently as parents have become increasingly concerned with the number of children experimenting with the substances.
Snurf pills are just one of countless fashionable legal highs that teens can get their hands on either in stores or, more conveniently, over the Internet.
Online stores have been pushing legal highs on Internet users for years, but until now there was never much concern about the dangers of legal highs. They are legal, after all, so parents had assumed that the substances were harmless.
However, all that changed in Pennsylvania recently when four school children were admitted to hospital after having taken Snurf pills. Parents reacted by seeking out information about the pills and trying to close down websites from which children can buy them without any restrictions.
Experts have been left stumped as to exactly what Snurf pills may contain, but some have looked at the effects of the pills and suggested that the main ingredient may be dextromethorphan (DMX), the cough suppressant found in a lot of medicines.
Perhaps most alarming to parents is the fact that it is suspected that about one in 10 kids has abused DMX before.
Herbal highs are popular alternatives to harder drugs, although the effects of one legal high to another vary considerably. Salvia divinorum has long been a popular legal substance, sold in smoking shops and online stores.
Salvia gives the user an out-of-body experience and makes him or her have extreme hallucinations. Some users say that experimenting with salvia changed their outlook on life, while others have told of being so terrified that they vowed never to touch salvia again.
Less intense is herbal ecstasy, which comes in various forms and may give users a slight buzz.
