The problem is that in many western cultures suffering is being regarded as a virtue and happiness as a great sin especially if achieved by using substances rather than through other actions. You can glaringly see that where people with chronic pain are denied access to medicinal cannabis, for example here in the UK. You can only receive treatment through a private medical clinic which costs hundreds and sometimes thousands per month, so it is only reserved for the wealthy. NHS says there is no evidence it works, so they will not refund any treatment and in the meantime thousands have to resort to asking gangs for supply. If it doesn't work then why people take it? Do they fake chronic pain to get high?
