What is An early sign of drug use

Explanation:

While every person’s experience of drug use or addiction is unique, there are some signs that are common to many people who abuse substances, including the following:

1. Intense cravings.

2. Tolerance.

3. Withdrawal symptoms.

4. Physical dependence.

5. Engaging in increasingly risky behaviors.

6. Drug-seeking behaviors.

7. Financial trouble related to drug use.

8. Neglecting responsibilities.

9. Developing unhealthy relationships with those who support addiction.

10. Isolating behaviors.

For anyone who has a few or all of these signs, finding quality drug and alcohol addiction treatment is an important first step. Beginning with a detox period, treatment usually progresses to either an inpatient or outpatient program and is followed by comprehensive aftercare.

Chances are your teen's mood swings can be attributed to the racing and changing hormones that come with adolescence. In other words, teen mood swings are normal. You'll want to pay attention, though, if your teenage son or daughter is experiencing mood swings along with changes in behavior or appearance, such as:

Losing interest in activities they once enjoyed

Dropping old friends for a new group

Acting despondent, aggressive or angry

Sleeping more than usual

Breaking rules

Exhibiting physical changes like sudden weight loss, frequent nosebleeds, bloody or watery eyes, or shakes and tremors

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
