Ok here goes:
Actually, the discovery of the THC receptor site and the subsequent research and observations it has inspired conclusively refute the hypothesis that marijuana is dope.

Many important brain functions which affect human behavior involve the neurotransmitter dopamine. Serious drugs of abuse, such as heroin and cocaine, interfere with the brains use of dopamine in manners that can seriously alter an individual's behavior..... a drug's ability to affect the neural systems related to dopamine production has now become the defining characteristic of drugs with serious abuse potential.

According to the congressional Office of Technology Assessment, research over the last 10 years has proved that marijuana has no effect on dopamine-related brain systems....NONE

Marijuana should no longer be considered a serious drug of abuse because, as summarized by the OTA "Animals will not self-administer THC in controlled studies ..... Cannabinoids generally do not lower the threshold needed to get animals to self-stimulate the brain reward system, as do other drugs of abuse." Marijuana does not produce reinforcing effects....

The definitive experiment which measures drug-induced dopamine production utilizes microdialysis is live, freely-moving rats. Brain microdialysis has proven that opiates, cocaine, amphetamines, nicotine and alcohol all affect dopamine production, whereas marijuana does not.......

Research has enabled scientists to know which portions of the brain control various body functions..... and this knowledge has been used to explain the pharmacological properties of drugs that activate receptor sites in the brain.

There is a dense concentration of cannabinoid binding sites in the basal ganglia and the cerebellum of the base-brain, both of which affect movement and coordination. This discovery will aid in determining the actual physical mechanism by which THC affects spasticity and provides therapeutic benefits to patients with multiple sclerosis and other spastic disorders.

This is just getting started. The Pros greatly outweigh the Cons in this wonderful......GOD GIVEN......plant.
So before you start hating.....remember this....
