I would just like to weigh in with all of those freezoners who say that Hubbard never took drugs. There is no evidence of that at all.
Excluding the eyewitness testimony from individuals such as Dart Smohen who actually worked directly with Hubbard and have reported on it, and taken along with Hubbard's many personal claims to have "researched" drugs.
But hey, they could be wrong.
Hubbard himself is certainly known to have lied regularly. As to those who wish to believe Hubbard didn't have experience using drugs, almost all of them had no actual experience working with the man. The few who did were not typically working at close quarters with him, unlike Dart, Gordon, Alan, etc., instead they were onsite but not in intimate circumstances with Hubbard.
