Worth noting that a gram of coke currently goes for a nationwide average of around 100-150 USD in Switzerland, and about 200-250 in the US, per the data I looked up.
Different supply levels of and ease of access to various drugs make them comparatively more or less expensive. Combine that will a user base of above-average wealth and it makes sense.
I agree regarding the absolute value of the two drugs though. Coke is fine, I suppose, but nothing I want to shell out the money for - but then again, I’m not in Switzerland so who knows.
