The consciousness-expanding drugs - the hallucinogens, such as cannabis, mescaline, LSD, Psylocybin - I think are useful to a writer up to a certain point. That is, they open psychic areas that would not otherwise be available to the writer. But I feel that once these areas have been opened and the writer has reached them, he is able to get back there in the future without the drug.
