Scientists are now able to actually see this happening. The Brookhaven study, which included researchers from State University of New York at Stony Brook and Columbia University, examined PET scans of 17 current cocaine users. Researchers found that high doses of cocaine blocked from 60 to 77 percent of the users' dopamine transporter sites. (For the user to perceive cocaine's effects, about half of the sites had to be blocked, the study found.) Methamphetamine, or speed, produces a similar effect, dramatically boosting the supply of dopamine at brain synapses, this therefore giving adolescents a nice feeling of relaxation which is much the same sort of feeling you get after a few nights on the brewski's, but the difference with drinking is that it is accepted by society. .
Recent studies show that drug education programmes in schools are 'not working'. .
Dr Lawrie Elliott, head of research at the University of Dundee's school of nursing and midwifery, wants schools to rethink policies on tackling drug misuse among adolescents. His opinion was follow a $128 million education campaign called Know the Score which aims to give every pupil information on the risks of drugs. .
However, Elliot said there was no evidence that schools-based prevention programmes stopped children taking drugs. .
Drugs prevention programmes in schools don't have much of an impact on adolescent taking dugs. The current programmes do not seem to work! .
Last month a report showed that almost every school offers drug education. Pupils are given information about tobacco, alcohol, solvents and controlled drugs and are taught how to refuse offers of drugs. .
The new findings from executive-funded research was carried out into the most effective way to reduce drug taking, and will warn that school programmes have little effect on young adolescent who have already started taking drugs and will inform them that the best way to get rid of the problem is to find out the reason why adolescents started using drugs for.
