Marijuana is a powerful man made hallucinogenic drug..
Shiploads of all of these..
Manmade and man harvested and man managed.
None of these exist in your natural diet.
Head off into those woods and areas where you live and tell me what you find of any of these.
No wheat and no milk and no juice and no honey.
No caffeine and no alcohol and no nicotine.
No marijuana either.
Now eat and drink what you do find.
Water and meat and fish and birds and insects and plant life..
Everything that you choose to eat.
Babies put everything in their mouth to see if they like to eat it.
All humans do the same thing.
