Here are the steps to use a cigarette roller:

1. Gather your materials: rolling papers and tobacco.
2. Load tobacco into the roller by clicking the roller into the down position and sliding one of the rails down until it clicks.
3. Even out the tobacco.
4. Roll the cigarette by tucking the edge of the paper into the tobacco crease and applying more pressure with your thumbs while rolling your middle fingers upward.
5. Seal the cigarette by wrapping the paper all the way around the tobacco without creasing the bottom of the paper.
6. If you're using a hand roller, fill it with tobacco and pack it before feeding in the paper.
