I would say alcohol, definitely. Alcohol is physically addictive, and cold-turkey withdrawal from it can easily kill you. You can also overdose and die on it fairly easily. Alcohol is literally a poison.
Marijuana, on the other hand, cannot kill you unless you smoke so much of it that you end up with lung cancer. Its physical effects on the body are minimal. It's virtually impossible to overdose on it, and even if you do manage to overdose on it, you most likely will not die. And since it is not physically addictive, there are no physical withdrawal symptoms.
Salvia is just like weed, but it doesn't show up on drug tests.

You don't. You could buy K2 or Salvia, or some other legal alternative to use in place of weed, but generally if it's not weed, it's just not weed, there's no substitution.
No. Salvia can not show up as marijuana in an urinalysis because there is no THC in it. However, depending on the organization that is providing the test, you may fail it. Check your organization regulations and if they do not mention anything about salvia, then you are allowed to partake until they make a rule. So I don't recommend asking your boss because he or she may think about making it a reason to fire you.

Weed, Ecstasy, Salvia, LSD, and DMT. other various pills and research chemicals…
No. There is a video of Miley Cyrus smoking Salvia, a substance that is legal in California.
I'm not sure why this question is under "Ecstasy", but Salvia is a legal herb in the mint family known for causing severe halluciniations. You can smoke it like weed and the high supposedly lasts for 5-15 minutes. Salvia on its own is not very potent, but the salvia you buy at the smoke shops has added chemicals that increase the potencey by salvia by my estimate of 10.
yes.
