I know many heavy and moderate recreational ketamine users and 90g is completely absurd.the really heavy users I know go through a gram per day max. During parties or festivals it can be more. Not to say that there isn't a big difference to therapeutic use.

If I do the math right, that’s like $5k/month or more. I doubt many recreational users consume that much. Not for long anyway.

You tend to get deals on bigger purchases. But it's a pretty typical pattern for people to destroy all their savings, and social capital very quickly during the escalating dose phase of drug addiction. My friend who got hooked liquidated his retirement funds, sold his car, house, borrowed tens of thousands from family & friends & banks, committed insurance fraud, and embezzled from his employer. Probably over $100K and all gone within 18 months to ketamine and meth.

I think it's worth reevaluating the word 'recreational' here. Except for festivals, or longer parties as someone already mentioned 300mg is an enormous amount to consume in one sitting, especially without a good understanding. 90g per month seems quite unsafe.

You could k-hole every night for a month IM'ing 100mg, and that'd still only be 3,000mg. 30 grams of ketamine is an absolutely crazy amount.

Sorry, those numbers are for monthly consumption.
