No, it is not true that LSD can be put on the back of a stamp. LSD is listed by the UN as a Schedule I substance, meaning that it has no recognized medical uses and a high potential for abuse. Furthermore, it is strictly illegal in most countries and placing LSD on the back of a stamp would be a violation of any applicable laws.
