An influential doctors group is beefing up warnings about marijuana's potential for teens. The American Academy of Paediatrics' is issuing the new guideline for doctors and parents about the risk of using marijuana.

According to CNN, the advice comes in a new report from the American Academy of Paediatrics' on Monday. The research group opposes the recreational marijuana use for kids.

Dr.Seth Ammerman, a researcher from American Academy for Paediatrics emphasizing that message is very important because most states have legalized medical use for adults. At the same time, many have also decriminalized or legalized adult's recreational use. Those trends have led parents to increasingly ask doctors about kids use.

AAP News and Journals has reported, the brain continues to develop until the early 20, which makes concern about the potential short-and long-term effects of a mind-altering drug. The research report suggested that teens that use marijuana at least 10 times a month develop changes in brain regions affecting memory and the ability to make the future plan.

Besides this, some study report suggests that starting marijuana at a young age is more likely lead to addiction than starting in adulthood. All teenager users develop these problems and some may be more vulnerable because of genetics or other factors.

The US government data show that almost 40 percent of high school student have tried marijuana, about 20 percent are current users and about 10 percent first tried it before the age of 13. The recent data showed that the users are increased in recent years among those aged 18 and kids aged 12-17 increasingly think that marijuana use is not harmful.

However, the doctor stated that parents should avoid using marijuana in front of their kids and should keep all marijuana products store out of kid's sight. The drug is no longer helpful for the young children.
