Don't snort it. That couldn't be good for your nose or sinuses, and if you snorted some down into your throat or lungs, you'd be miserable and also might have to seek medical treatment. Eating weed works if the stuff's prepared correctly, but the high is much milder, not stronger, unless you eat a lot of it. (People who want to get good and high from an edible source do a lot better eating hash.)

It took me a long time to get high, too, when I began smoking. Like probably seven or eight tries. I think some people are simply resistant to it, but I know for a fact that lots of folks simply take a little time to get their cannabinoid receptors activated and working before they feel effects. If you're sure you're inhaling correctly and breathing smoke down into your lungs so the absorption can take place, then just be patient and try a few more times to see if those receptors aren't just taking their sweet time. Make sure you have some decent weed, too.
