Answer:

between-subjects design

Explanation:

According to my research on different experimental designs, I can say that based on the information provided within the question the best way to make sure that the internal validity will not be influenced by an outside event is to switch to a between-subjects design. This type of design is an experiment design that has two or more groups of subjects each being tested by a different testing factor simultaneously. Since they are done simultaneously it significantly reduces outside influence.

A friend of yours is considering taking up vaping and says that it is totally safe, because she plans on getting the nicotine-fr
hammer [34]

Answer:

Vaping impacts the developing brain.

Kids’ developing brains are more susceptible to addiction and e-cigarettes essentially provide a smoke-free way to inhale nicotine, which is more addictive than heroin, cocaine or alcohol. Some brands of e-cigarettes contain a dangerously high level of nicotine – more than twice what is found in traditional cigarettes and other e-cigarettes. Nicotine mixed with a developing brain can lead to addiction, reduced impulse control and mood disorders. Nicotine also negatively impacts the prefrontal cortex, the area of the brain responsible for attention, decision-making, judgement and planning.

Nicotine is equally dangerous for adults and has a negative impact on heart health.

Nicotine can:

Increase blood pressure and heart rate

Narrow arteries

Lead to heart attack by contributing to the constricting of the arterial wall

Many vape pens are also used to inhale THC, the main psychoactive ingredient in marijuana. The Centers for Disease Control and Prevention (CDC) suspects that exposure to THC, as well as a mix of THC, nicotine and vitamin E, an additive in many vape carriages, is causing serious lung injury.

Vaping has been linked to lung injury.

As of September 2019, 530 cases of lung injury and seven deaths due to vaping have been reported in the U.S. Symptoms of vaping-related lung injury include:

Rapid onset of coughing

Breathing difficulties

Weight loss

Nausea and vomiting

Diarrhea

Physicians have attributed these symptoms to a buildup of oil and/or white blood cells in the lungs. THC and CBD, another active ingredient in cannabis, are heated up as oil in vape pens before being converted to vapor to smoke.

If your child exhibits any of these symptoms and uses a vape pen, bring them to the emergency department with the pen and the cartridge they used immediately.

Vaping misconceptions cloud its danger.

It is a marketer’s dream, and a parent’s nightmare.

Kids have a misconception that vaping is harmless.

The pods come in a variety of kid-friendly flavors that are more attractive than the taste of tobacco.

E-cigarettes are small and easy to hide. The JUUL looks like a flash drive and can be easily concealed in a pocket or hand.

Vaping is easier to do indoors, such as in bedrooms, school bathrooms and even classrooms, without detection.

Vaping has become quite common, and kids are exposed to classmates and images of famous people vaping, making it “cool.” Peer pressure drives kids to try it, and then they become easily addicted.
