A study by University of Saskatchewan researchers suggests beneficial aspects of smoking marijuana at least among rats, who appear to have sprouted new brain cells and besides benefiting from reduced depression and anxiety. The study's results appearing in the 'Journal of Clinical Investigation' have actually given a fillip to the traditional and mythological view that associates the addictive weed in some ways with immortality.

The Canadian researchers led by Xia Zhang, suggested that the illicit substance marijuana actually may promote new brain cells in region of the brain called the hippocampus that is associated with memory. They concluded that marijuana was possibly “the only illicit drug whose capacity to produce increased neurons is positively correlated with its (anti-anxiety) and anti-depressant-like effects”.

For the study, the researchers injected laboratory rats two times everyday for 10 days with HU210, a synthetic cannabinoid chemical (obtained from marijuana) and evaluated them against a normal group. The rats that underwent the HU210 injections developed new nerve cells in the brain's hippocampus dentate gyrus region of the brain that facilitates memory development. The injections also appeared to counter depression and anxiety, but could not be held as 100 percent akin to smoking marijuana, which the researchers felt would require additional studies.

Zhang suggested that the study did indicate that marijuana could have its medical uses particularly “for the treatment of anxiety and depression”. But these results are unlikely to buy the favor with the US administration or the possibility of legalization on medical grounds. In fact only recently the US Supreme Court ruled against marijuana growth or possession for medical reasons.

Unlike most addictive drugs that are known to inhibit the development of new neurons, causing loss of memory and impairing learning on chronic use, it appears that marijuana or ganja may actually be the mythological “elixir of eternal life” that Indian gods churned from the oceans. A sharp contrast from ordinary addictive substances, the researchers suggested that marijuana's neurogenetic properties may actually be unique given that the rats showed some correlation between their cannabinoid treatments, the increased nerve genesis and their altered stress or anxiety levels.

Marijuana that has traditionally been used by many cultures over centuries “for medical and recreational purpose”, as the researchers suggest appears to be able to modulate pain, nausea, vomiting, epilepsy, stroke, cerebral trauma and variety of other disorders both for humans and animals alike. But it maybe several more studies before the mysterious benefits of marijuana that currently stand shrouded in tradition and mythology, become accepted by the modern scientific world.
