yea crossfading is definitely fun, but you gotta be careful. i always drink before i smoke, but it really depends on how much you drink. If I've had like like 5-6 drinks (which for me a little buzzed) and then I smoke, its awesome cause it just amplifies and intensifies your high. but if your shitfaced (like for me bout 12 or more drinks) and you smoke, you will get the spins and probably throw up.
