The effects of marijuana reach different parts of the body along with the brain, irrespective of how it is used.
Since marijuana includes hundreds of chemicals, it leads to hundreds of additional compounds when burned. When abused or used indiscriminately, marijuana use may lead to side effects such as memory and learning problems, loss of coordination, paranoia, panic attacks, problem solving difficulties, and distorted perception. It is important to note that marijuana use is not lethal when compared to alcohol. Since the initial effects of marijuana wear off on their own after an hour or two, the use of marijuana is relatively safer than of other drugs.
But, marijuana chemicals remain in the body for much longer and this may mean that marijuana may still be present in your body after four days if you had taken one milligram of THC, the primary ingredient of marijuana.
However, medicinal marijuana has been found to be great value for stopping convulsions, reducing muscle spasms, eliminating menstrual pain, stimulating appetite, and to treat health complications such as HIV, AIDS, cancer, glaucoma, multiple sclerosis, and epilepsy. This is just one of the reasons why marijuana has been considered as the best and safest drug known to the mankind as the drug has never taken a life on its own in the history of human beings.
