should i start drinking alcohol?

so its the title, im 19 and ive always wanted to do substances such as smoking,drinking alcohol and shrooms. and now the feeling just intensified like i keep thinking abt what would happen if i start doing these things. also im not really starting it to “fit in” or due to fomo infact none of my friends do these but the moment i heard “no one has to live life sober” from somewhere ive been thinking more of doing these things. what r ur opinions?
