Is there research that some people interpret their own way?

Actually weed can and does lead to more drugging,even if it's only Alcohol,the legal stuff.A substance abuse is anything that
you are dependant on.Medications,cigs,weed,coke,heroin,
c.meth,a bottle of mouth wash.This changes you Mentally,Spiritually,and Physical.Can send you to prison.

Only alcohol? Alcohol is a hard drug, people can use it for mild intoxication, but that drug has the potential to kill and has killed many, and uh your question is confusing. Could you please restate your question or ask it in a different way? Are you saying that the drug effects can change someone in a way that will send them to prison? Okay and then?

okay.

Right on. Oh ya, I feel it.

Of course. Research is not always fool proof.

Smoking marijuana CAN lead to more drugs, but not always. There is research regarding a predisposition to addiction as well. I know several people who smoke weed, but have never bothered with any other drugs. They've been smoking weed for about 10 years now, so if they were going to try something else, they would have by now.

For every research paper, there are three that are opposing. Some facts cannot be denied, like gravity. Others are conditional.

Yes, people can twist to suit their purposes, for both good and bad. But also, people base a lot of opinions on their experiences, which mine is that I started my drug use with cocaine, and the last thing I ever tried was weed and alcohol, so I don't believe that weed always leads to worse drug use. And my best friend smoked weed for five years before she decided to stop to get a better job, but she never moved on to any other drug, even drinking or cigarettes, so, I don't agree with you. Sorry if this wasn't what you wanted to hear, but that's what I believe. But basically yeah, people can twist research. But then again, take that a step farther, people that try to assume why research came out a certain way can also twist facts, but they do so because of their own experience too. So, go figure.
