A few common symptoms from Marijuana detox are:
Insomnia
Insomnia is the most common symptom of withdrawal during marijuana detox. This effect can last for a few nights of no sleep or for a few months of occasional sleeplessness.
Depression
Depression is another common symptom along with nightmares and vivid dreams. The reason being is that marijuana usage hampers the dreaming mechanism, so when you are no longer under the effects of marijuana, your dreams come back with a crash. These dreams can be highly emotional, vivid, and continuing even after waking up and going back to sleep. It usually takes a week for these dreams to begin. Then, they last for about a month and then taper off. A common theme of these dreams is the use of marijuana and can recur for years.
Anger
Anger is also a common symptom of marijuana detox. The range of this anger can go from a slow burning rage to irritability to sudden bursts of anger. Anger at the world, loved ones, oneself, or being an addict are emotions that are felt during detox. Emotions can bounce back and forth between anger, euphoria, and depression. Fear, anxiety, increased or decreased sex drive, or a loss of a sense of humor can all be experienced during marijuana detox. Usually by three months, these symptoms fade to normal emotions. During the first week to first month, a loss of concentration can also occur. This can affect the ability to learn new material, but fortunately does not last.
Headache
Headaches are the most common physical symptom of marijuana detox and withdrawal. These headaches can last from a few weeks up to a couple of months. The first few headaches can be very intense.
Night Sweats
Night sweats can also occur during the first month. Sweating is an effective way for the body to get rid of toxins. A person may sweat so much that an unpleasant odor may occur requiring an extra shower or bath.
Phlegm
Another way for the body to clean itself is the coughing up of phlegm. This cleansing can last up to six months, but is a good sign that the body is healing itself.
Eating Problems
Eating problems also accompany one third of addicts who are detoxing from marijuana. Loss of appetite, digestion problems, cramps after eating, nausea, and occasional vomiting were reported by some who were detoxing. By the end of the month, most reported no more eating problems.
Tremors or shaking along with dizziness is another symptom reported. Less frequently reported symptoms experienced were impotency, kidney pains, chronic fatigue, hormone imbalances, and minor eye problems were usually resolved by the end of two months.
