Rashi and Urmila makes laddoos, some with bhaang (for Ahem) and some without bhaang (for Jigar). So, i think, Radha will change the bhaang ones meant for Ahem with the normal laddoos which are meant for Jigar. Thus, Jigar will get intoxicated instead of Ahem.
INTERESTING, isn't it? Last time Rashi got intoxicated and this time it's Jigar.
