So if you are doing your best writing under the influence of drugs or alcohol (mind altering substances), how can you say YOU wrote the poem? Did that substance write it? You obviously wouldn't have written it without that influence (as you say) so who gets the credit (or the blame)?
Sharon, I can say I wrote it because it was my hand, my mind and my thoughts. Drugs play an incredibly small part in the things buried in my mind. I would have written the same thing with or without drugs. How do I know? Because I make the comparisons and the only things that differ are the content. Obviously the person is going to get the credit because the drugs/alcohol didn't write the piece, the human being did.
What if there were no drugs? No alcohol? Would you stop writing?
Which definition of drugs were you after? Caffeine can be labelled as a drug. Are you going to say the same thing about people who are addicted to caffeine? Or nicotine? Because we all know that too much of those substances causes a person to hallucinate. I wouldn't stop writing even if I wasn't taking the things that I do. Like I said before, it's the person that writes - not the substance.
