Animal tests have shown that extremely high doses of marijuana are needed to have a lethal effect. In fact, tests show that you would have to consume 40,000 times as much marijuana as you needed to get stoned before you will overdose. Thatamp;rsquo;s a ratio of 1:40,000. Lets say you would get stoned from 1 joint, that means that you will need 40,000 joints in one sitting to have an overdose of marijuana. Now lets take alcohol, the ratio on alcohol varies between 1:4 and 1:10 depending on the personamp;rsquo;s health. So if you would get drunk from half a bottle of whisky, 2 bottles later you could die from an overdose of alcohol. In America, every year 10,000 people die directly from an alcohol overdose and alcohol related deaths are 110,000 deaths a year. Included are drunk driving, fights, drownings etc. No one ever died from a marijuana overdose.
