Your love's nothing but a poison:
DEADLY.
Your love's nothing but an alcohol:
INTOXICATING.
Your love's nothing but a drug:
ADDICTING.
Your love's nothing but a cigarette:
DANGEROUS.
Your love's nothing but a scrape:
PAINFUL.
Your love's nothing but a wish:
HOPING.
and
Your love's nothing but a battle:
WORTH FIGHTING.
