LOL, smoking on a rollercoaster, how sad! I'm sorry unless you're an inconsiderate asshole please don't bother. Anyways, I know a better idea, take a little ziplock bag of grass and wave it around, won't that be funny!
Do you feel like you have to ruin some non-smokers fun by placing a leaf with tar inside and lighting it on fire?
Go nibble on a nicotine patch.
