Material preparation: sketch paper, pencil, eraser, colored lead or watercolor pen.

1. First, draw the outline of the boy's head on a blank sketch paper with a pencil. Hair is wavy, ears are semi-oval, and cochlea is painted. The lines are smooth and soft.

2, plus a serious and angry expression, the eyebrows are pressed down and the eyebrows are upturned, and the eyes are wide and oval, and the eyes are going to draw the gods. The upward protruding lines draw the boy's simple mouth.

3. Then, draw a neck with a suitable size, and then draw a polo collar and a red scarf, as shown in the figure.

4. Then draw the dynamics of two arms. One hand holds the schoolbag tightly, and the other hand makes a refusal gesture. Short sleeves should also be painted completely here.

5. Then, finish the body and the schoolbag. Short sleeves should conform to the physiological age of boys and be slightly wider than the shoulders. If you think it is a little difficult to draw the schoolbag, you can subtract it and not draw it, which will reduce the difficulty.

6. Next, draw a drug prohibition symbol, that is, two concentric circles, one with a large diameter and the other with a small diameter, but not too different, so as to draw in, and then draw various drugs in it and write "poison" to highlight the significance of the symbol.

7. Draw a rich picture of green plants, birds and white clouds in the blank space of the picture. You can draw tulips, grass, sparrows and white jade to draw waves. You can add the title "Reject Drugs" and this anti-drug children's painting will be drawn.

8. Finally, use colored lead or watercolor pen to color the drawings, which can be played freely, but the words and signs of refusing drugs should be red to play a warning role.

Anti-virus methods for teenagers:

Seriously accept the education of drug abuse prevention;

There are many cases in which teenagers don't know what drugs are when they first come into contact with them. Instead of staying at a respectful distance from others, I am full of curiosity about them. Therefore, when society, schools or parents introduce their knowledge about drugs, they must accept it seriously. You can even learn about drugs by actively surfing the Internet and reading books.

Form independent personality and establish correct three views;

Through the analysis of the data, we can see that some teenagers can't help but get spiritual support by taking drugs when they are frustrated and empty, even though they know the harm of drugs. In the prevention of drug abuse, teenagers need to form their own independent personality, not be advocated by others, and have their own independent judgment. We should also abandon bad values such as pleasure and showing off.

Make friends carefully:

From the sociological point of view, peer groups play a very important role in the socialization of teenagers. In the frequent interaction with peer groups, teenagers can easily acquire the values and behaviors of other members. Teenagers must be careful to make friends and stay away from friends who take drugs.
