How to rehab yourself

Are you smokers? I find this great litle post about marihuana. I think that medical bosses start its ilegalization cause uf its medical purposes.
Here is a post i find :

The hazards and benefits of cannabis written tens of thousands of pages of conflicting opinions, but some medical effects can not be ignored. However, regular marijuana smoking seems creates some kind of habit, because research Australian scientists has shown that quitting regular cannabis just as traumatic as quitting cigarettes.

People who regularly consumed cannabis had a variety of symptoms that reduce their ability to work and relationships when they decided to quit.

Some of them include irritability, loss of appetite and mood swings, almost the same as the symptoms of nicotine withdrawal.

The most extreme cases have included depression, and better success in rehab to people who have had symptoms such as mood disorders, physical tension and insomnia than those who were tired and had night sweats.

I know someone of you think that it is very iregular to smoke it but i dont think its too bad.I think it should be on each person choice would he do it or no.
