Shag, also known as baccy, rolling tobacco or loose tobacco, 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' fabric 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. These were imported to the United Kingdom by Rory Innes following the Virginia tobacco plantations in North America.
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, tailies, tailors or straights.
