Anyone that argues against legalization on the grounds that weed is a gateway drug is totally full of shit. Here's the crux of their bullshit: 99+% of all heroin (or other hard drug) addicts started by smoking weed, therefore it's a gateway drug. Well no fucking shit Sherlock! This is the posterchild example of how statistics can be misused. The honest assessment of "gateway" status looks at the statistics the other way around. What percentage of people that have smoked weed go on to become heroin addicts? The answer...less than .1%. Conclusion: Sorry, not a gateway drug.
