"Are there any risks for teenagers using marijuana?"
Thanks for your question. The answer depends on what condition for which the cannabis is being used. There are benefits and drawbacks to using any medication, including pharmaceuticals, over-the-counter, and natural or alternative medications. Cannabis, though generally safe, does have side effects and can be harmful in certain situations. I do not recommend using cannabis recreationally for teenagers. Cannabis can affect the developing brain and cause lasting side effects into adulthood.
