Yes, some people can have experiences like that. There can be a few other side effects as well. The same as side effects listed for any other medicine, they won't be experienced by everyone, and different people may experience different levels of side effects. Just read the labels on most antidepressant or anti-anxiety medicines and you'll see anxiety is listed as one of the side effects for those as well. (It's always seemed kind of funny to me that most anti-anxiety medicines list anxiety as a possible side effect of using that medicine.)
One notable side effect that you'll see listed on almost every medicine in the event of overdose is death, and for many it can be a side effect in a small amount of cases even at a proper dosage. That is one sideeffect that is totally absent from marijuana. So it's legal to take drugs in which you will have all the side effects that might occur with marijuana as well as many more than won't occur, and yet it's still illegal to use marijuana in most locals.
As far as withdrawal symptoms, that only occurs with chronic long term usage. The same type of withdrawal can occur with sugar, caffiene, tobbaco, alcohol, and almost any other substance your body gets used to after long term chronic use. There is a huge difference between the withdrawal symptoms associated with stopping marijuana use as compared to what is considered a physically addictive substance. Stop using marijuana, sugar, coffee, soda pop and you might have real cravings, if you've been a chronic user you may even feel bad and you may even have headaches, stomach aches, and other minor problems.
Compare that to opiates, and many anti-depressants and anti-anxiety medications. The withdrawal from those substances can cause serious health risks which can require medical assistance. Heroin withdrawal for instance is so severe it can cause death. The same is true of many commonly prescribed medicines, that's why you're often told not to stop using some medicines except on your doctors order and under their supervision.
The fact is any individual who is prescribed any prescription drug is at risk of many more and much more severe side effects than someone using marijuana. In fact many things that are brought up about the dangers of marijuana, are also experienced with chronic use of substances like caffeine, tobacco, or alcohol.
I'm glad you understand that the things you brought up in your reply, are things to be aware of, but don't justify the prohibition that's been in effect for the last 70 years.
