I agree with you science nowadays is mostly junk. On the other hand if we can choose to ignore any study that links X to something bad, then this is a conversation not worth having.

Myself I like to err on the side of caution, since my country has free healthcare which means I have to pay for the mistakes of others, so I don't want them making mistakes in the first place. They should feel free to smoke all the weed they want and become psychotic drones in the fucking Congo
