Anxiety as a result of Marijuana Withdrawal?

I’ve smoked for about 2 years, although I rarely smoke more than 2 or 3 times a week. However, over the last few weeks, I’d say that I smoked 4 or 5 times a week. This past week, I was unable to smoke marijuana, and on the third weed-less day, I seem to have had a pretty severe panic attack. I started breathing really heavily, and felt overwhelmed by feelings of stress and anxiety, and I was crying uncontrollably. This lasted for about 15-20 minutes. Afterwards, I still felt anxious and stressed, but the physical symptoms had calmed down. Is it possible that this is connected to marijuana-use? I’ve never heard of withdrawal symptoms, but that is the only out-of-the-ordinary change I’ve had in the days leading up to the attack.
