Tipsy obviously knows nothing about cannabis.
First off, it is not physically addictive in any way shape or form. Some may say that it can become mentally addictive, but then again, so can shopping, gambling, codependency, exercise, etc. And, if someone who has been drinking heavily for several years is suddenly deprived of alcohol, they CAN die, because they are physically addicted and have the possibility of going through withdrawl symptoms known as the DT's. People who have smoked cannabis for a long time when suddenly cut off from it have no such problems.
Second, there ARE many medical studies to support that it is beneficial for seizures, Alzheimer's (both are brain diseases that are the result of misfiring neurons), and cannabis has been proven to help, which makes me ask the question as to why people still believe that it kills brain cells. Especially when it helps with brain dysfunctions.
As far as alcoholics not being willing to drink because they know they are alcoholics, even after 50 years sober? Well, that is because heavy drinking will reduce a certain enzyme in the body, and it has been proven that without enough of it, even just one drink is enough to set up the phenomenon of craving that is prevalent in addicts. People who smoke cannabis are able to have one joint and then walk away because there is no physical craving that results from cannabis use.
Yeah, there was that ONE incident in Denver where some guy walked off of a balcony when he was high because he ate too much of a brownie, but that was because he didn't understand how it would affect him, nor did he (probably) follow the instructions of the cannabis seller to go lightly. But then again, if he'd drank a whole bottle of Scotch, the same result could be expected.
And finally, no................you CANNOT overdose on smoking alone. You will go to sleep and wake up the next morning feeling great if you smoke enough to make you sleepy. With alcohol, you CAN overdose, and many times it happens when some kids make it to 21 and their friends take them out for drinking as much as possible. Ever hear of alcohol poisoning? It's when you OD on alcohol.
But................not everyone is capable of looking past the Reefer Madness propaganda that they learned as a child.
And...............fwiw..............cannabis is not a hallucinogenic, it doesn't cause you to see things that aren't there. The colors might be a bit brighter, and you might notice things you wouldn't normally, but every thing you see while high is what is real.
How do I know all this? For the last 8 years in the Navy, I was a Drug and Alcohol Program Advisor, responsible for screening and making recommendations to the command for anyone that appeared to have a substance abuse problem.
And...........at the tender age of 38, a year or so after I'd retired from the Navy and did some more research to find out what all the hype was about, I finally tried cannabis and have found it very relaxing, as well as better than alcohol. Beer and whiskey will give you a hangover the next day if you drink too much. Cannabis won't. And, there have been times where it has dried up in the area I live in and I had to wait a couple to three weeks before I could get some more cannabis, and I never went through any kind of withdrawl.
But.............closed minds like Tipsy like to live in fear and try to scare everyone else into their way of thinking. My recommendation? Try it before you start demonizing it, or at least talk to people who have used it and find out what the REAL effects are, not just the hype and lies you've been sold since the racist Anslinger pushed to have it illegal because he hated Blacks and Mexicans (the primary consumers of cannabis), and wanted a way to lock them up legally. That's the reason he commissioned Reefer Madness, he wanted to scare everyone off of it.
