I think some people might not know how much that is...
For reference if you buy coke in a club or something you're usually buying it in 1g or 0.5g. With a steady pace of use (couple of bumps a hour) that can easily keep you going all night and at 1g and you'll still have some left. Even this one girl I knew who had a serious coke problem was only doing like at most 2 grams on a wild night out (and certainly not on consecutive nights...).
25g even over a long weekend and even sharing is going to end in a hole in your nose... at the least you're looking at amphetamine psychosis.
Yeah getting drunk every night, doing open polyamorous relationships, and having a shit load of coke on you is something you get over in your 20s, not when you're married, with a house and a bunch of kids running around.
