Luiz, must be a changed username
I just read an article that said that the smell is the number one reason why growers get busted. I'm not an expert but I imagine there are ways to combat the smell.
Well, the smell isn't like tobacco, it doesn't cling to things (walls, perhaps lungs, etc). Take away the source and the smell dissipates completely in a very short time.
I wonder if a blood test can determine if a person was intoxicated or used cannabis recently?
Well there are a lot of legal drugs that can get one high. Codeine (used in some pain killers and cough syrups) metabolizes to morphine (though I imagine those medicine require a prescription). I believe a lot of anti depressants are similar to ecstasy and a lot of ADD medicine is similar to amphetamines.
Anti depressants are almost nothing like ecstasy. Both increase levels of seratonin but the effect is very different--and not because of dose levels/magnitude. A lot of ADHD medicines
are amphetamine. Even methamphetamine is (rarely) prescribed for ADHD. Amphetamine and methylphenidate are the two main ADHD treatments. One you know as Adderall, the other as Ritalin. Methylphenidate gives an almost identical reaction as cocaine. Both amphetamine and methylphenidate work, among other reasons, by releasing dopamine in the brain.
Codeine, vicodin, oxycontin, morphine, percocet, heroine, methadone etc are all derived from opium.
Ambien will mess you up beyond anything. All the "ambien walrus" memes exaggerate nothing down to the idea that you could be seeing a talking walrus. And unlike other "real" hallucinogens, you don't even know you're tripping like that and might not even be conscious at all.
Standard Robitussin cough syrup, active ingredient DXM, is a drug in the same family is ketamine and PCP. It's a dissociative and hallucinogen, and doesn't require that much more than the dose to be on something.
Diphenhydramine aka Benedryl will also get you high. Most people don't realize it at normal doses unless they are tuned into that thing, but at higher doses its very obvious.
Yeah, basically drugs are drugs, and some are legal and some aren't, and it doesn't make any sense.
