The latest investigation in lancet psychiatry proved no evidence for an adolescent marijuana use incensement being depended on legislative permission of its consuming for medical purposes. The experiment led by professors from Department of Epidemiology, Columbia University, used the method of survey in about 400 schools to build a model of marijuana use among about one and half million students during the previous month and included information from 25 years of the problem analysis.
The results suggested no significant difference in usage prevalence before and after medical marijuana law passage, with rates in the 8th grade prevailing even before the legalization.
Being a controversial subject, whether the passage affects adolescent marijuana use, it is being constantly researched in many states. However this experiment in contrast to former ones had precise attitude towards such factors as individual, school, and local characteristics as well as monitoring long study period considering 21 states where law had passed until 2014.
Amanda Reiman, manager of Marijuana Law and Policy for the Drug Policy Alliance and professor at UC Berkeley, is sure this could be the answer to long debates, where opponents use risk of increasing number of adolescent using marijuana not to pass the law which hinders access for sick and pain-suffering.
At the moment more than a half states, including Colorado, Oregon, Washington in the last years, have legalized the usage of medical marijuana. The law which allows consume for medical purposes in other States is already supported by many Americans and is waiting for ratification. Each of these laws points out that sales and provision are permitted strictly for adults and restrict any efforts for spreading teen marijuana usage.
Worldwide experience has also proved that law legalizing marijuana for medical use doesn’t lead to unpropitious consequences, as it was in the Netherlands, where no connections between decriminalization and growing percentage of teenage use were mentioned. Reform defenders also state that not consume statistics should be evaluated as the main indicator of the policy actions but decrease of arresting because of simple possession and other problems connected with marijuana prohibition.
