Should people on probation smoke salvia?

It depends. If a person on probation is anticipating routine drug tests, some consideration should be taking before using salvia. In most US states and countries, salvia is legal, so an person on probation may legally smoke it if they wish. Even if a person resides in a place where salvia is illegal, it is not commonly tested for. However, getting caught with salvia in a state where it is illegal can impact your probation. Other than legal issues, whether or not a person uses a substance depends on their individual values and preferences.
