More and more, teens have been using over-the-counter cough syrup and other cold medications to try to get high. This is called "pharming."

As a result, some pharmacies in the U.S. have chosen to move these medicines from the general aisles to behind the pharmacy counter so they see who's purchasing them.

Chances are, if you had asked for three bottles of cough syrup, you would have raised some suspicion. Same thing goes for diet pills, some of which contain a very low dose of amphetamines (speed).

There are lots of problems with using these types of medications to get high, not the least of which is a person has to consume a LOT of them before they "work." Many cough syrups still taste pretty nasty, so is it worth it to drink three bottles of the stuff to get a slight buzz?

Pharming also causes dry mouth, loss of body fluid, itchy skin, blurred vision, hallucinations, nausea, vomiting, heart problems, high blood pressure, numbness of fingers or toes, redness of face, headache and loss of consciousness. In rare cases, it can kill.

Basically, people should only use cold medicine when they have the sniffles, and they should only take it in the prescribed amount.
