is cannibas harmful ?

cannibas is the plant that used as a drug, hash is made of cannibas.

cannibas may also be called ( ganja, marijuana, weed,... and others)

All forms of cannibas have negative physical and mental effects.

Several
regularly observed physical effects of cannibas are a substantial increase in
the heart rate, blooshot eyes, a dry mouth and throat, and increased appetite.

Use of cannibas may impair or reduce short-term memory and compehension, alter
sense of time, amd reduce ability to perform tasks requiring concentration and
coordination, such as driving a car. Motivation and cognition may be altered,
making the aquisition of new information difficult. Marijuana can also produce
paranoia and psychosis.

Because users often inhale the unfiltered smoke deeply and then hold it in
their lungs as long as possible, marijuana is damaging to the lungs and
pulmonary system. Marijuana smoke contains more cancer-causing agents than
tobacco smoke. Long-term users of cannibas may develop psychological dependence
and require more of the drug to get the same effect. The drug can become the
center of their lives.

in my opinion i think that cannibas should be legalized like tobacco or alcohol... they are also harmful, but the freedom must be above everything... so like bob marley's song legalize it :P
