Shag, also known as rolling tobacco, loose tobacco and rollies is fine-cut tobacco used to make self-made cigarettes by hand rolling the tobacco into rolling paper or injecting it into filter tubes. It got its name from the finely cut strands appearing like 'shag' and was originally considered poor quality. Various types of cut are used; most shag blends use a simple mixture of cutting styles, consisting mostly of loose cut but also krumble kake, ribbon cut and flake may be used. Some shag blends use cuts reminiscent of pipe tobacco.
A cigarette made with shag tobacco may be called a rollie, a roll-up/dole-up or hand-rolled. The flat bags in which shag is typically packaged for commercial sale are often called tobacco pouches. Oppositely, pre-processed and packaged cigarettes may be referred to colloquially as tailor-mades or straights.
