Although im not a very 'spiritual' person(damn i hate that word), i do firmly believe that natural drugs, especially ones that have been found or grown by the user(magic mushrooms, marijuana, coca, poppys) are 'better for the soul'. I always feel better and have a better trip knowing where my drugs came from, what they are, and what they will do. The idea of eating a pill to get high or trip.. doesnt appeal to me in the slightest.
Now, thats the fruity, irrational explanation.
That rational explanation:
1: Safer. Although chemicals(cocaine, mdma, lsd, heroin, etc) are 'safe' if your source is 100% legit, and you KNOW for a FACT that what your getting is infact what your buying. However, for 99% of drug users, this isnt the case. They buy drugs off people they barely know, of whom the dealers have bought their drugs off people they barely know and so on. A natural drug generally comes in a natural form, like nuggets of weed, and thus you know what it is.
2: Peace of mind with certainty of drug. We all know that pondering on whether a pill you ate that did nothing is going to give you liver failure in a month isnt any fun. Neither is having your trip turn bad because what youve eaten definitly isnt LSD and is lasting 18hrs.
3: Price, availablity: Because natural drugs are just that, natural, they can be grown by a user, or else they are grown by people, usually locally. So supply is abundant, and cheap. There isnt any processing or expensive equipment involved, so its easy too, and usually natural drugs have a lower schedule/class, so its not so hush hush and hard to get.
4: Economically sound for your country: Importing heroin from afghanistan doesnt help your economy, buying some opium from an old lady who grows it in her backyard is. Also, alot of hard drugs like heroin and cocaine keep poor people poor, and cause these people to be exposed to terrible chemicals and live relatively shit lives.
5: Less addictive due to lack of purity. Coca leaves dont cause people to sell there family to slave lords, cocaine does.
6: Good for the environment: The processing involved in creating man made chemicals, usually involves the creation of bad toxins, and because this is done illegally, they cannot be disposed legally. So they are dumped in parks or gutters, leaching into streams and killing wild life. Natural drugs create oxygen, help bees do there thang, and generally 'make the world go round'.
