Yes: If you do not have a reliable source of marijuana, then you should not smoke it, precisely because it can be cut with lots of things - including synthetic cannabinoids like spice or k2, methamphetamine, phencyclidine (pcp or angel dust) and many other things. Methamphetamine can raise blood pressure and pulse, cause palpitations and other heart problems, and make people paranoid.
