life is unpredictable .. make the most of it. you really have no idea what will happen so, why waste it avoiding everything simply because something bad MIGHT happen.
although to the OP its never wrong to discourage some one you care for if you really feel thats your prerogative.. other wise if you feel she deserves to make up her own mind, leave her to it. thats entirely up to you and nothing anyone says in here should really effect how you feel about it.
Also, if you're interested in the legal history of cannabis in the US and how it was federally outlawed (nevermind states' rights or amending the constitution to federally ban something).
In some cases sure, cannabis can make you attentive or cautious. It can also make you spaced out and unattentive. I've smoked before, I know the effects so cherry picking and deflecting to alcohol, (when we're discussing cannabis) as bad as I think that is too, isn't going to work.
Tobacco is much more harmful the smoking weed?Then explain Tobacco? You want to knit pick Alcohol, then explain Tobacco or Caffeine. Why is that shit allowed to be on the market, but weed isn't.
Not so mature yourself if you go through your sister's private shit. A case of "holier than thou", here, in my opinion, especially since there's nothing wrong with smoking some pot (I'd be way more pissed if my sister went through my stuff or phone without my knowledge than her smoking a joint, tbh). It's legal or tolerated in quite some countries for a reason - i'd be more worried if my sister would say she'd go drink until she's so drunk she can't stand, which is what most people do regularly. More unhealthy, and more dangerous.
Also, for that long of a post, you sure didn't say very much. :/ I mean if we only disagree on the number of deaths that can be traced back to Marijuana as a direct cause (not suspected contributor, that's a BS statistic and I hope you or anyone who's taken a statistics or polling class knows), there's really no need to waste focusing on anything else. Did you see my FDA and CDC links?
I think it's hard to argue marijuana with people in this thread because unlike them... I'm an advocate and know the ins and outs of marijuana at a biological scale... I know the 2 main chemicals in weed are CBD (Cannabinoids) and THC (Tetrahydrocannabinol)... CBD's give you the typical couch lock, munchies and body high... but they also reduce the rate at which cancer spreads and they slow down the process of memory loss diseases. THC is more of the actual drug affect that people do it for... It's related to the euphoria, mental highs... zoning out... detailed imagination etc... There are two types of plants, Indica which is CBD dominate and only has a flowering state of about 1-2 months... The other plant is Sativa which is THC dominant, but has a flowering state that can take as long as 3 months... which is why you're more likely to find an indica on the streets because it's quicker to grow and sell.
When you know the plant fairly well... it's hard to be scared of it, especially when the media tries to portray it as some devil drug. If something scares you, like weed did to me as a kid... you have to find the knowledge on your own and make your own decisions... I was told growing up that weed is horrible and that you can be addicted to it like alcohol... I believed them without questioning, until I decided to find the truth on my own... which is something people should do, not only for weed, but everything.
