Ah yes, gorilla biscuits, lol!! That's what we used to call 'em, back when you could actually get the real pharmaceutical grade Lemmon 714's. After 1984 they were completely removed from the market and made a Class 1 drug in the U.S., but they had effectively disappeared from the street by the late 70's. Too bad, I loved the hell out of them!!! They were a sedative/barb whose effect was actually quite a bit like being drunk, but without the sloppiness/puking/hangover afterwards, etc. And they tended to make girls horny as hell --- or at least they made them lose their normal inhibitions
I guess the closest thing I can think of currently available would be something like Xanax or Valium, but neither of those is really quite the same either. It's hard to describe taking 714's.
I used to work at a bar as a barback when I was 17. There was this REALLY hot bartender who also happened to deal in 'Ludes. I know she got me to drive her around one night going from bar to bar selling them. At each bar we would go in, she would order me a Jack and Coke (legal drinking age was either 18 or 19 at that time, I don't remember which) and hand me a 'lude under the bar. In a bit she would come back and we would leave and go to the next bar and repeat the process. At some point I blacked out but kept on going for apparently most of the night. I woke up about 7:30 the next morning naked in bed with this chick (she was like 24 at the time) with a REALLY sore dick, lol. I got up to leave as quietly as possible and realized that HER HUSBAND was passed out on the couch in the other room!!! Talk about awkward!!!! I made a safe escape, but couldn't walk right for several days, lol. I also discovered later that I had about 20 'ludes in my pocket, so I have no idea how many bars we hit that night! The funny part is, I still run into her from time to time (we still live in the same town). She left her previous husband and ended up marrying another dude I worked with at the bar. Her husband never found out anything (I later found out she had slipped him some stuff so he pretty much slept for like 36 hours straight!!!). She thought the whole thing was funny as hell, and still jokes about it! Those Lemmon 714's I ended up with in my pocket that night were the last REAL ones I ever saw because the Doc who was supplying her got busted. Anything I have encountered after that was fake (usually just crushed/pressed Benny's, but it isn't hard to spot fakes once you've seen the real deal!).
I guess there might be a lab somewhere in another country making them, but I've never heard of it if they are. It's probably a good thing. Blackouts were quite common on 'ludes. The problem was, you would keep right on going, sans inhibitions, and not remember jack shit the next day!! I have several friends that totaled their cars while on 'ludes and didn't remember a single thing about it!!!!
