Studies show that using cannabis under age 25 can affect how the brain develops. The damage can affect the person for the rest of their lives. Using under age 25 can affect memory, learning, attention, judgement, and decision-making—never mind how it affects the rest of the body.

How much cannabis, how often, and how you use it will affect how much and how long it can affect your health:

• Lungs – Vaping cannabis can damage the lungs. Second-hand cannabis vape is at least as harmful—or more harmful —than tobacco vape.
• Goals and performance – It can have a negative effect on how you do at work, school, and on your hobbies and activities. This is especially true for teens and young adults. Younger users have higher rates of being suspended, skip more school, and drop out more.
• Memory and learning – It can affect your memory, learning, and attention.
• Judgment and decision-making – It affects judgment and can lead to risky behaviour and poor decision making.
• Mental Health – In some, especially teens and young adults, using cannabis often can increase the risk for mental health problems like depression, anxiety, and psychosis.
• Dependency – Some studies show that early, regular use may be associated with a higher risk of addiction.
• Other health risks – It can affect both the unborn and newborn baby. Toxins to cannabis pass to the unborn baby, and then in the breast milk after birth.

According to the Council of Chief Medical Officers of Health " the safest approach for people who use cannabis is to avoid smoking or vaping cannabis extracts." 

• Teens and young adults have a higher risk of becoming addicted to nicotine.
• Stopping vaping may be harder for people who mix nicotine with cannabis because the combination may make nicotine withdrawal stronger.
• People who vape cannabis and nicotine together have more breathing problems than those who use only nicotine vape because of the increased exposure to harmful chemicals, including vitamin E acetate.
• There can be more problems with memory and learning.

The lung problems related to vaping weed is called E-cigarette/Vape Associated Lung Injury. EVALI for short. The CDC in the US has confirmed that EVALI is happening to people using vape products. Most have used THC with the thickening agent vitamin E acetate.
