Shore SERIOUS ISSUES REMAIN CONCERNING MARIJUANA Many of the points made in the June 25 editorial "Marijuana on the Table" are well taken, but there are other important issues to consider. First, the much higher potency of the active ingredient, THC, in today's marijuana renders it a powerful drug that can induce significant impairment in motor and cognitive abilities, including those having to with operating a motor vehicle. Secondly, the use of any intoxicating substance is especially problematic in younger people. Full development of the brain does not occur until approximately age 22. Use of mood-altering chemicals by teenagers can have significant adverse consequences on brain development. Third, smoking any substance inevitably causes respiratory problems. Fourth, for many individuals, marijuana is a gateway drug and leads to other serious addictions. Finally, federal law still considers marijuana to be a Schedule 1 (illegal) drug, and there have been court decisions that have supported employers in terminating employees who test positive for THC, even when it is the result of "medical" marijuana.
