Ur brain lays connections untill ur an adult, still lays them then but almost none. In the age of 1 to 6 I think you lay the most connections in ur brain because you learn a lot! After that it is less and less. Teenagers still lay connections and cant do that when intoxicated. That means they wont be able to use their brain at full capacity how it shouldve been (and thats why we have a minimum age for drugs). A lot of people wish they stopped as teenagers and you shouldent kind of encourage this behaviour with this comment. Some of my friends use it and I feel like they aint getting smarter of it.
