I agree with everything you said, definately, but you're a bit mistaken in this paragraph. Mixing LSD with marijuana is perfectly safe, as is alcohol. I wouldn't recommend mixing it with alcohol because they just don't go together very well, but you're not going to OD or anything. In fact, LSD just isn't the same without marijuana.
Prescription medication, or any pills at all, are the most dangerous thing. First off, if you ever buy pills from someone, look at the letter/number sequence on the pill, and Google that sequence to find out what the pill you have actually is! If you're buying ecstasy, most ecstasy sold comes with atleast one identifying mark on the pill, google it. Go to erowid.org, just don't blindly eat it without looking it up first. And never mix alcohol with any pills, ever. Marijuana is perfectly fine to mix with any drug, as the synergy of the two drugs together will not negatively effect you.
I can't believe I didn't mention this in my previous post, but first and foremost when it comes to experimentation guys
BE SAFE!. I've known a few different people who have died from the result of mixing unsafe drugs or ODing and I miss them every day. (Also, please do not follow the path I have taken in reference to drugs; stay as far away from cocaine and heroin as you possibly can).
Visit erowid.org for any other drug information you might be curious about, without a doubt the number one source on drugs on the internet, with
real data and experiences, and not the bullshit US government stance that smoking a joint supports terrorism and is equivalent to 9000 cigarettes. Don't ever listen to that propaganda bullshit.
