Rolling up is a technique used to combine multiple smaller amounts of a substance into a single, larger amount. It is commonly used with tobacco, where smaller amounts of loose tobacco are rolled up into a paper to form a cigarette or cigar. Rolling up can also be used with other substances, such as cannabis, where it is rolled into a joint or blunt.
The benefits of rolling up include the ability to control the amount of substance being consumed and the ability to create a more consistent and even burn. Rolling up can also be a more discreet way to consume a substance, as it can be done without the use of pipes or other paraphernalia.
