The short-term effects of marijuana include problems with memory and learning, distorted perception, difficulty in thinking and problem-solving and loss of coordination.

Although more studies are needed on the impact of marijuana concentrates, it is clear that in order to prevent use by youth, public education and awareness of the potential health risks are critical.

The expansion of medical marijuana laws has resulted in negative consequences. Teen use rates are significantly higher in states with medical marijuana laws compared to other states. Moreover, youth perception rates of the harmful effects of marijuana have significantly decreased in states that have legalized medical marijuana.

Whole or crude marijuana (including cannabis oil or hemp oil) is not approved by the U.S. Food and Drug Administration for any medical use.

Is it really appropriate for an electronic sign to be placed beside a business whose majority of customers are children? (Story, Sun Journal, May 27). Free speech or not, is that really the message the community wants to send to its children?

Maybe the sign could be changed to read “A strong positive mental attitude will create more miracles than any wonder drug.”
