I did read very critical article from J. M. Keppel Hesselink.
Here are his conclusions:
"Smart drugs available via the Net are of increasing concern. Their efficacy in healthy individuals is not proven and the proof offered on the Net is of a simple structure and is not peer reviewed. Most arguments are based on extrapolation of in-vitro or in-vivo animal experiments or are based on epidemiological data. Proof of the efficacy and safety of many of these drugs has not been generated in well controlled, methodologically sound experiments. The arguments supporting the use of smart drugs as boosters for all kinds of functions must sound like sweet music in the ears of the consumers, but the dark sides of the recreational use of these drugs is not discussed sufficiently at all. Especially psychiatrists and family practitioners should be aware of this source of drugs, since many of these drugs have a narrow therapeutic margin and can interact negatively with a variety of other Rx drugs. The problems of side effects, abuse and dependency are rarely discussed on the Net, and only the sunny side of the use of smart drugs is advertised.
The recent recommendations of the WHO concerning the sale and advertisement of medical products on the Net should be taken seriously, and more offensive strategies to inform public and health workers about smart drugs should be developed. "
What are your feelings about the issues?
