Negative effects of alcohol??

i just found out that my 13 year old brother drinks, and i'm worried about him and want him to stop. he's way too young and immature. do you know of any negative effects of alcohol that might worry a teenage boy?

yes alcohol leads to loss of self control n awareness
therapy is required
do not delay please

Juvenile detention. thats a big one, threaten him with it. kids are told everything bad that can happen and mostly they just dont care. i didnt. i had my first drink when i was 13, got raped at 14, got in trouble with the cops at 15, and at 16 i had mostly quit, but my grades sucked and pretty much everything else was screwed up. and by 17 i was pregnant. boys cant get pregnant but still. threaten to throw him in juvy. that should do it.

everything about a 13 year old kid drinking is negative!!! He needs to stop!! He's way more likely to become an alcoholic. Not to mention he's still growing, and Im sure it doesnt help that!
Its just not the kind of thing that 13 year old boys should be doing....try to get him involved in something else, and maybe he'll forget about it!! haha Or maybe some kind of sport where he'll get into trouble if caught drinking. If he gets involved enough maybe it'll give him incentive to stop!

Negative effects:
1. Impaired cognitive functioning-cannot make good decisions
2. Slurrish speech
3. Long term brain damage-the brain is still developing in the frontal lobes till you're twenty two
4. Acting out of character
5. Losing short term memory
6. Having blackouts
7. Inability to concentrate on school
8. Impaires athletic performance
9. Hangovers
10. Headaches
11. Lower grades; missed classes=lead to academic failure
12. Vomiting
13. Addiction; alcohol=drug
14. His brain will probably be damaged by the time it stops growing if he keeps this up
