Salvia - 6/10. It sure did work - my reality was warped for a while after that. However, it wasn't aesthetically pleasing. Also, after the one time I did it, I found out from my friends that I was thrashing wildly around the room that we were in, and I would have launched myself out of a window if my friends hadn't restrained me. Definitely made me never want to take it alone, and the effects from the drug weren't enjoyable enough to try it again anyway.
Fake weed/spice - 6/10 to 8/10 - Depending on the brand, I have actually gotten pretty good highs from this stuff. On the high end, I've gotten regular munchies and had good, heightened, 'high' vibes from hanging out with friends and listening to music. However, it's nasty stuff, and I figured that it wasn't near worth it after a month or two. Didn't take long at all for me to go back to my trustworthy marijuana instead of dealing with this synthetic crap. Also...I started using this at the end of 2010 to the start of 2011 - I'm pretty sure that laws at the end of 2010 prohibited some of the chemicals that initially went into this 'fake weed' so I could never get used to the new shit that was being made.
Nutmeg - 5/10 - I've only done it once, three years ago, so detailed specifics are lacking. It did give me a feeling of being high somewhat akin to smoking a lot of schwag weed, but nothing outstanding like smoking high-grade cannabis. Works in a pinch. It's main plus is that it lasted for 6-8 hours, which is pretty outstanding. However, I didn't really care for the high so I never bothered to try it again.
(Just for the hell of it...I'm going to do alcohol too...)
Beer - 4/10 to 9/10 - Depends on the brand. Smooth and calming. Fun to do in the summer - should be pretty self explanatory. The hangovers prevent it from being a 10.
Liquor - 8/10 - Can't stand the taste and I don't like the burning side-effects, but it really does get you drunk and fast. Although I don't really like to drink it, due to the taste and its potency, I have to give it a pretty high rating because it does what it says it will, and it's a good time if you're in the right mindset.
