In early 1970, an unsigned memorandum distributed to Philip Morris’ top management read, “We are in the business of relaxing people who are tense and providing a pick up for people who are bored or depressed. The human needs that our product fills will not go away. Thus, the only real threat to our business is that society will find other means of satisfying these needs.”

A hand-written letter from Philip Morris president George Weissman read, “While I am opposed to its use, I recognize that it (cannabis) may be legalized in the near future…Thus, with these great auspices, we should be in a position to examine: 1. A potential competition, 2. A possible product, 3. At this time, cooperate with the government.”
