Anyone who develops or sells nuclear weapons and anyone holding stock in those companies (former advisor or not) benifits from the testing of nuclear weapons.
Defense contracts include the costs of R&D which is why they are so lucrative for a business to take. By testing nuclear weapons those companies holding the contracts can bill us the taxpayers for their tests. To put in other words for every nuke they test is somewhere from 20 million to 100 million of taxpayer money going to a defense contractor pocket.
As much as I hate to say this, MDMA being used for treatment of mental illnesses might not be viable option because of it’s negative effects. I do not know if short term severe depression and long term memory loss is worth a reduction in PTSD. Maybe as a last resort medication similar to how methamphetamine is prescribed for drug resistant ADHD.
