look up any word, like the eiffel tower:

Ativan (Lorazepam) is an Antianxiety agent - a benzo - used to relieve anxiety, insomnia and other related disorders.

More expensive and addictive than most other benzodiazepines, doctors are reluctant to prescribe it, when there are cheaper and safer drugs available
I'm gonna take an Ativan and go to sleep.

Perscription name Lorazepam, but also sold in the US under the names Alzapam, Ativan, Loraz, Lorazepam Intensol.

Lorazepam is an anti-anxiety agent under the general category of “benzodiazepines”, or “benzos,” meaning “mild tranquilizers,” used for the relief of anxiety and, sometimes, to relieve insomnia. Often it is prescribed to calm people with mania / schizophrenia, or given intravenously as a sedative to help patients ease the anxiety that frequently is found with withdrawal symptoms. It has less of an effect on the liver then other benzodiazepines, making it a good choice for patients who are going through rehab and taking anti-abuse drugs.
Seriously, man. Rehab ain’t like the old days with the Methadone clinics. They usually give you something like Ativan, calm yo’ ass right down, you don’t feel no pain from the withdrawl. Seriously, check it. Could get you off da shit for once and for all.

an anti-anxiety med that relaxes you to the max. although you do not trip or hallucinate from it, you can get super high to the point where you can't remember how to spell certain words and you forget your own name. It's also a short-term memory eraser so the next day you won't remember shit.

but it is super potent and dangerous, so, you've been warned.
"i had to order your food for you at Racine's because the waitress thought you were mentally retarded."

"why?"

"because you were so fucked up on Ativan that you couldn't even talk in complete sentences and garrett was laughing his ass off. you embarrassed me."

"oh. I don't remember that."

ativan.
