Wrong. Marijuana has plenty of addictive properties. This is from Brown University: No one would argue that marijuana is as addictive as alcohol or cocaine. However, it's wrong to say that it is not at all addictive. More and more studies are finding that marijuana has addictive properties. Both animal and human studies show physical and psychological withdrawal symptoms from marijuana, including irritability, restlessness, insomnia, nausea and intense dreams. Tolerance to marijuana also builds up rapidly. Heavy users need 8 times higher doses to get the same effects as infrequent users.
For a small percentage of people who use it, marijuana can be highly addictive. It is estimated that 10% to 14% of users will become heavily dependent. In 2006 marijuana was responsible for 16% of all admissions to treatment facilities in the U.S. Because the consequences of marijuana use can be subtle and insidious, it is more difficult to recognize signs of addiction. Cultural and societal beliefs that marijuana cannot be addictive make it less likely for people to seek help or to get support for quitting.
If there is no problem with smoking marijuana and functioning normally, then why do most companies drug test? Let me ask you this, do you think it would be ok for a crane operator, airline pilot or school bus driver to do their job while high?
