Plants have always been used as a source of medicine, so why not use medical marijuana to help patients?
If we are honest, most of us think of marijuana or weed, ganja, chillums, cannabis, pot, skunk, and any number of alternative names (see marijuana slang) as a drug that induces feelings of happy tranquillity. The truth is that the most active constituent of marijuana, THC (tetrahydrocannabinol), has some very useful medicinal effects.
For instance, its ability to inhibit vomiting makes it extremely useful for treating patients receiving chemotherapy, while its tendency to increase appetite bestows great potential in the treatment of eating disorders, such as anorexia nervosa.
Considering that cannabis contains over 60 psychoactive compounds, it ia a little wonder that some of those will be potentially useful in the treatment of various medical ailments.
In fact, you could argue that it would be negligent not to investigate the plants potential to make medicine, do not forget that many of our most effective medicines are plant based, aspirins chemical name is salicylic acid, and it was discovered after noting that many ancient cultures chewed willow bark for pain relief; the cardiac drug, Digoxin, was discovered over 200 years ago when English physician, William Withering, noted that the foxglove plant could help patients suffering from dropsy (fluid retention).
Why do you think society has been so anti medical marijuana, yet many other plants have been used for medical reasons?
