how can i quit vaping easily? i’ve tried exercise, hanging out with friends and trying to distract myself but nothing seems to work and i always end up going back to it... at this point my chest hurts constantly throughout the day and i’m concerned about my lungs. i’ve been vaping for 2 years now but i’m not even in the right mindset to quit. any ideas?

Answers

Answer:

i think in order to stop vaping like put vasline on the thing so it doesnt taste good and every time you do it it might gross you out of it? if that doesnt work maybe you should try and turn to some hobbie that is theraputic like writing and drawing everytime you think of vaping? im sorry im not much of a help

Answer:

Vaping is bad for your health and has a long list of negative side effects. So the first step to quitting is to stop buying it when you feel like you want to. So whenever you find yourself wanting to buy it stop yourself and have self control over the urge.Vape is made to be addictive so thats why it's hard to stop all at once. For every day that you complete your goal in not vaping congratulate your self or reward your self or tell your friends that you are not vaping for (amount of time) that way you cant back out of it. For instance stop vaping for one week at a time then focus on two weeks and so on.This way your mind will gradually get used to it. And for each time period reward your self with something you like (I know this sounds childish or something but this tactic has results).

Im no expert at anything but heres my take on it. Have a wonderful day.

What alternative and complementary medicine practices have you used (or would you use)? What are the advantages or disadvantages to the practice that you used (or would use)?

Answers

Answer:

Hi there, alternative and complementary medicine deals with herbs such as herbal plants to treat a cold, acupuncture, and massages. It is a term for medical products and practices that aren't part of standard medical practices.

Explanation:

Advantages- Helps both the mind and body (can be used for both physical and mental therapy), very cheap, helps with personal attention (such as back pain this type of medical practice helps with that low cost)

Disadvantages: No regulation (not a lot of Health Organizations such as CDC doesn't recommend it), has long term treatments (If you have cancer the medical procedure in this medical practices takes longer than any cancer screening and treatments in regular medical practices) and it isn't useful for emergency medical treatment.

1) Why do you think many young people take risks like Jayme did?

Answers

Answer:

whatd jayme do

Explanation:

Many young people take risks for a variety of reasons. One possible reason is that during adolescence, the brain undergoes significant changes that can affect decision-making and risk-taking behavior.

What is decision making?

The process of making choices by identifying a decision, gathering information, and evaluating alternative resolutions is known as decision making.

For a variety of reasons, many young people take risks. One possible explanation is that the brain undergoes significant changes during adolescence, which can affect decision-making and risk-taking behaviour.

The prefrontal cortex, which controls impulses and makes decisions, does not fully develop until the mid-20s.

Adolescents may be more likely as a result to engage in risky behaviour without fully considering the consequences.

We don't have enough information in Jayme's case to speculate on the specific reasons for her behaviour.

It is critical to remember that each person is unique, and there is no single explanation for why young people take risks.

Thus, due to this, many young people take risks like Jayme did.
