Paranoia is a side effect of smoking pot. As evidenced in this thread

I recall reading that
using too much marijuana, which is quite common, can induce transitory episodes of paranoid manifestation in
individuals who are predisposed to the disorder.
The underground status imposed on marijuana by its prohibition has resulted in widespread ignorance about many aspects of this extraordinarily useful and beneficial plant. One such aspect is dissemination of information pertaining to potency variations and dosage recommendations, all of which would be readily available if marijuana use were legal. As it is, the use of marijuana is typically confined to surreptitious distribution of largely unknown potencies the primary usage method of which is the familiar rolled cigarette ("joint"). All-too-often the entire joint is smoked with no concern about its potency.
If marijuana were legal it would be dispensed much in the way beverage alcohol is, providing the consumer with a broad variety of potencies (proofs) and potential effects. I.e., one has the choice between beer, wine, cognac, or tequila. And awareness of the potential effects of each type are widely known or available on request.
In the example of alcohol, one ounce of tequila has the approximate intoxication potential as does eight or ten ounces of wine or four cans of beer (depending on individual tolerance levels). So lighting up a joint or bong-bowl full of highly potent marijuana and smoking the whole thing is analogous to drinking a wine glass full of tequila.
The bottom line to optimal recreational use of marijuana is knowing the potency of what you are about to use, knowing your limitation, and not exceeding it.
