Quitting weed can cause withdrawal symptoms, but fortunately, they are not physically dangerous like some other drugs. The severity of the symptoms can vary depending on factors such as how long and how frequently the person has been using weed. Some common withdrawal symptoms include:

• Irritability
• Anxiety
• Depression
• Insomnia
• Strange or unsettling dreams
• Decreased appetite or weight
• Headaches, nausea, vomiting, sweating, and flu-like symptoms

These symptoms usually peak about four days after quitting or cutting down and can last for up to several weeks. However, they will probably be more intense if the person stops completely rather than cutting down and if they smoke cannabis every day or most days.

Its important to note that someone who has long been accustomed to using weed to mitigate their depression or anxiety might not have the tools to cope with these feelings while sober. The rebound of anxiety or depression after quitting weed can potentially lead to relapse.

On the positive side, quitting weed can deliver substantial benefits, including physical and mental benefits such as improved memory, mental acuity, and attention span. The timeline for these benefits can vary, but some positive changes happen right away, while some may take a few weeks or months.

If someone is experiencing severe withdrawal symptoms, they should undergo medical supervision as they detoxify.
